We have dreamed up the vehicle of the future drawing on suggestions

from both the small and large screen. In the 80s, we were excited to see

how Michael Knight, star of Knight Rider, fought injustice by driving a

high-tech car, the so-called KITT (Knight Industries Two Thousand), whose

artificial intelligence made this autonomous vehicle the ideal co-pilot.

The batmobile also attracted our attention with aerodynamics that imitated

nature (a bat) and enhanced its tremendous speeds. Nature was

also the inspiration for the gull-wing doors of the DeLorean DMC-12;

however, it wasn’t its design that fascinated us in Back to the Future, but

its function as a time machine capable of disappearing in a shower of

sparks and reappearing amidst blue flashes.

Science fiction has shaped our collective imagination, so that the real

revolution of the automotive industry seems to us to be represented by

flying vehicles traveling through our city skies. And although the necessary

technology already exists, regulation is the great obstacle for this

innovation to be implemented; therefore the near future of this industry

is aimed at providing efficient electric, autonomous and permanently

connected cars.

Whether it parks or lands, the vehicle of the future is intrinsically linked

to photonics. So the development strategies of automotive companies

now involve the use of increasingly advanced sensors that aid autonomous

driving, sophisticated laser systems and vision cameras that improve

production and highly evolved communication systems that constantly

connect traffic and infrastructure, among other innovative light

Volkswagen Navarra

is opting for the latest

developments in machine vision

With an investment of 1.2 million euros, Volkswagen

Navarre has launched an artificial vision tunnel with cutting-edge

technology. Located in the Paint workshop, the

new installation uses the images captured by 30 cameras

and 300,000 leds of lighting distributed in four arcs to detect

small irregularities in bodywork. The artificial vision

tunnel is a pioneer facility for Volkswagen.

All bodywork manufactured and painted in Volkswagen

Navarre passes through the new installation, which is 9.5

metres long, 4.1 metres tall and 4.4 metres wide. Each is

examined for 18 seconds inside the artificial vision tunnel,

where 5,400 photographs are obtained.

"With the use of powerful mathematical algorithms, the

computer searches the images obtained for possible

imperfections in the reflection of light, which would be

imperfections on the bodywork", explains Amaya Novoa

Grijalbo, of Paint Planning at Volkswagen Navarre.

Thanks to this new detection system, able to appreciate

details such as a drop of water or a fingerprint, paint polishing

operators can see the detected imperfections on

a screen, spending less time on their detection and thus

reducing visual fatigue, which tends to increase with the

consecutive passage of light coloured car bodies.

In the last six months, this commitment of Volkswagen

Navarre to ongoing improvement and quality in the painting

process has focused on adjusting all the detection

parameters to the maximum, correctly defining the irregularities

the system has to show. "This work requires periods

of adjustment, but it is necessary to ensure that the

tunnel is as efficient as possible," adds Novoa.

Francisco Rodríguez Funes, Paint Manager, explains that

"the artificial vision tunnel allows us to increase the quality

and capacity of the workshop, and also provides an

opportunity to improve prior processes, as it provides us

with a large quantity of information".

thereby covering the entire process. In this regard, some

of the main aspects of Nissan's work at the Barcelona plant

seek to respond to challenges such as autonomous driving,

Collaborative robots, 3D printing or

virtual reality are some of the solutions

that Nissan uses to respond to the current

challenges of the automotive industry.

digital connectivity and the growing number of zero emission

vehicles. Thus, the use of collaborative robots and

3D printing for some processes, the use of automatic

trolleys (Automated Guided Vehicles -AGV-) to move materials

in its factories, virtual reality and integrated flow

management are just some examples.

The Nissan Barcelona innovation ecosystem is committed

to a dynamic and continuously growing environment,

Photonic technologies are driving

the automotive industry

towards a bright future

Transportation was one of the great revolutions of the twentieth

century, completely changing the way we move around

our environment. Given the great impact that motor vehicles

have had on our lives, the automotive industry has always

used the latest technological advances to improve both

the characteristics of vehicles (safety, comfort, connectivity,

efficiency, etc.) and their production processes. Key in the

development of large numbers of monitoring, image and metering

devices, photonic technologies have become part of

the new revolution in the automotive industry, from two

very different perspectives: 1) improvement in the quality

and monitoring of production processes and 2) the development

and implementation of autonomous, clean and more

comfortable vehicles for the driver and passengers.

Regarding improvement of the production chain, photonics

is in an advantageous position compared to other technologies

in areas such as monitoring the quality of processes

by means of both standard and 3D imaging systems, or the

design and processing of materials by laser. On the other

hand, one of the challenges in clean vehicles is to create propulsion

systems based on new materials, and to improve the

current systems for filtering vehicle particles based on fossil

fuels; the use of light as a means of analysis is key in all these

challenges. The industry is also moving in the direction of

autonomous vehicles, and as smart as possible, for which

they need to use advanced high-speed imaging and data

processing systems.

One of the photonic technologies most used in the automotive

industry is laser, especially as a tool for processing

materials, which affects the entire vehicle, both exterior

and interior. In particular, one of the current trends is to use

materials that are more lightweight, while still efficient and

safe, and one of the most innovative approaches is the use

of multi-material structures. The basic idea is to replace part

of the metal compounds used in the production processes

with lighter ones, while maintaining the resistance and reliability

standards required by the industry, such as thermoplastic

compounds based on carbon fibre. In this sense, the

AIMEN technology centre is involved in the ComMunion project,

using laser techniques for both the control and precise

monitoring of material temperature, and for its high-speed

cleaning and texturing.

Progressing towards cleaner vehicles also requires more efficient

manufacturing processes, in terms of energy, reliability

and also speed of assembly. This is a perfect fit with the

opportunities provided by laser technology. The problem is

that metal materials absorb very little energy at wavelengths

at which lasers have traditionally performed best (typically

in the near infrared with a wavelength of λ≈1μm). However,

there are some very attractive proposals for solving this

problem, such as that carried out by Coherent-Rofin. With

their FL-ARM system they have redesigned the laser beam

profile to increase absorption of the material at these wavelengths

by a controlled increase in its temperature. Another

LIGHT! light! by by SECPhO secpho 11

current trend to improve the efficiency of laser welding of

metal materials is the development of systems that operate

at short wavelengths (below blue, λ≈0.45μm), where

the absorption of energy in metals is high and cutting precision

is also greater. In Spain, AIMEN and Laser 2000 are

leading the use of such laser welding technologies for the

automotive industry. Along these lines, also remarkable is

defect monitoring and laser welding geometry based on

high speed infrared cameras developed (and validated by

leading companies in the automotive sector, such as Volvo)

by New Infrared Technologies, in collaboration with AIMEN.

Additive manufacturing (or 3D printing) is also one of the

cross-sectional technologies that has had most applications

in the automotive industry, where it has been used

for a long time, especially in prototyping. Although chain

production is not expected to be completely based on 3D

manufacturing in the near future, the use of this technology

is expected to explode in the next few years as a low

cost solution for the design and chain production of small

parts where precision is of the essence. In particular, laser

metal deposition (LMD) is the standard method adopted by

leading companies such as Volkswagen or Nissan, for both

the development of prototypes and for chain production.

In order to accelerate the implementation of this technology,

AIMEN is carrying out the INTEGRADDE project, with

which it intends to create a control system for the parts

produced during the entire process.

Despite all these advances in manufacturing processes

and monitoring the quality of parts, there is always a percentage

of error that may require additional monitoring

during the manufacturing process. In the automotive sector,

a large number of metals are used, which are treated

by different heat processes that give them very particular

properties. For this reason, any deviation from the expected

temperature standards can ruin a whole part. Although

all production processes are usually monitored by artificial

vision, this does not precisely identify the temperature of

the material. Thus, complementary techniques such as thermography

(which analyses the temperature of a material

at different points by remote measurement of the infrared

radiation emitted) are making their way into the industry.

This is where they have focused part of their efforts at bcb,

where they have created a complete thermographic monitoring

ecosystem, bcbMonitor. Alternatively, in many cases

it is necessary to test manufactured parts in situ, which requires

additional portability and flexibility. In the case of the

automobile, it is not always easy to have a 3D measurement

system that shows that parts have been manufactured

without error. For this reason, portable, simple and reliable

solutions are being sought that allow parts to be scanned

in real time, which is what they have done at AsorCad with

their portable 3D scanning laser system.

Away from the assembly line, one of the great revolutions of

the first half of the 21st century, not only in the automotive

field but also in terms of technology and mobility in general,

is expected to be the development of autonomous cars, capable

of navigating without the active participation of the

driver. This means that the cars of the near future must be

equipped with smart vision that makes them capable of detecting

and identifying all the objects that surround them.

This implies the use of different types of sensors and vision

systems, including 3D vision systems, where LiDAR (Light

Detection and Ranging) has positioned itself as the best candidate

to be "the eyes" of the cars of the future. In LiDAR,

a pulsed laser scans the scene and, by measuring the time

it takes for the light pulse to be reflected by the objects in

the scene at different points, the 3D image can be reconstructed.

This technology, combined with object identification

algorithms, provides the possibility of autonomous and

12 light! by secpho

intelligent automobiles. However, LiDAR loses efficiency in

conditions with bright environmental lighting and, in order

to solve this problem, Beamagine have designed a LiDAR

system capable of cancelling out ambient light, enabling it to

operate at greater distances. In general, the LiDAR technology

must be complemented with a large number of optical

sensors that provide information about the distance to any

obstacle, changing the tonality of the rear-view mirrors in

high ambient light, adjusting the direction of headlights, etc.

All these sensors will give rise to a very high flow of information,

which must be transmitted at the fastest possible

speed, as it is essential to ensure minimal reaction and decision-making

times. The fastest physical means of communication

available to date is fibre optic, however economic

and resistant fibres are required so that it may be used by the

automotive sector. This is precisely the objective of KDPOF,

which has already positioned itself as a leader in the sector

thanks to the IEEE and JASPAR certifications, which will

enable its communication systems to be assembled in both

Europe and Japan.

The current trends in the automotive sector seek not only

clean and autonomous vehicles, but also the creation of

spaces where driver and passengers feel comfortable in all

possible situations. One of the options that have been explored

during recent years is to incorporate projection systems

in windscreens, showing any alert, speed, route map,

etc. so that the driver does not have to look away from the

road. If we add to this a system for detection and classification

of gestures, we could ensure that it is practically never

necessary to take our hands off the steering wheel, thus increasing

the safety of the vehicle.

The lighting of the vehicle also plays a very important role in

the comfort of passengers. Therefore, cars increasingly incorporate

a greater variety of interior lighting systems that

adapt to the requirements of passengers and outdoor lighting

conditions. To achieve the most natural lighting possible,

materials that precisely disseminate light are needed and, as

an example, CEIT has been working on the design of materials

by laser processing to generate zones with different

lighting tonalities The Leitat Technological Centre seeks to

control the amount of light entering the vehicle, through the

design of smart windows that adapt their opacity to the exterior

conditions and thus prevent the car from overheating.

Finally, we must not forget that one of the main sources of

innovation in the industry is the design, characterisation and

testing of new materials. While many of the tests, such as

mechanical or chemical tests, can be carried out in companies'

own research centres, more precise and detailed tests

require the use of cutting-edge technology. This is precisely

what synchrotron light, such as that generated in the ALBA

Synchrotron, provides, enabling the study of the behaviour

of catalysts for contaminating gases or the structure of new

materials, for example.

These are some examples of the implementation of photonic

technologies in the automotive sector, which represents

10% of the GDP and 19% of total exports, and which has always

been an area where Spain has been a leader in the sector,

as the 2nd largest car manufacturer in Europe (source:

InvestSpain). This, together with the key position of photonics

in Spain, ensures a bright future for the photonic-automotive

alliance in the coming years.

In Spain, research centres and companies that are experts

in photonics and are playing a vital role in the application of

photonic solutions for the automotive industry can be found

in the following areas:

pulse lasers

for automotive applications

Many times great innovations happen in the smallest of

details. Details that produce special comfort, that lead to

a better interior or exterior finish or that reduce friction

enough to save on fuel. One of the tools being implemented

in industrial production processes (and also in the automobile)

is the laser tool.

These tools have been used for a long time for welding processes,

but they are increasingly being used in other industrial

applications: drilling and cutting of materials, surface

thermal treatments, control of mechanical properties, joining

dissimilar materials, etc.

Within the wide variety of laser sources available on the

market, the most modern are known as ultrashort or femtosecond

pulse sources. The main characteristic of processes

with ultrashort pulse is the almost zero thermal affectation.

It is in the specific case of femtosecond pulses, which

have a duration of around 10-15 seconds, that this characteristic

manifests itself in all its potential.

The energy emitted by the laser is transmitted in such a

short space of time that it cannot be dissipated from the

electron network through the atoms, thus producing a direct

transition from solid state to gas, that is, sublimation

without producing any thermal change in the rest of the


The main result of this ultra-fast process is the ability to

perform processes with a very high resolution that could

only be dreamed of just a few years ago but is now available

to end users: resolutions in the one micrometre range

are achievable in most processes, falling to 0.2 in the case

of superficial processes.

Ceit has been working on femtosecond lasers for more than

ten years, and specialises in developing industrial applications

that tap into the capabilities of these lasers. In terms

of the automotive sector, here are two specific applications

that we have developed:


Modification of plastic elements for the

generation of lighting effects. Currently, ergonomics

in the interior of automobiles is

becoming a requirement for all new models that manufacturers

launch on the market. As part of this drive for ergonomics,

the interior lighting of the passenger compartment

is a very demanded effect, since the aim is to adapt it to

each type of driver, different exterior lighting (night vs. day)

or even different areas inside the passenger compartment.

In this respect, one of the effects most sought after by manufacturers

is to illuminate the interior from the roof of the

car with diffuse light, to generate a sense of comfort for all

occupants without adversely affecting driving. This effect

is achieved using light sources of different colours (usually

LEDs) depending on the selected mode (night, day, sports,

comfort, etc.), and projecting it through a sheet of transparent

material that diffuses it to specific parts of the ceiling.

In the case of wanting to project lights of different colours

simultaneously, one of the problems that arises is the need

to use different sheets and separate them to ensure that

each colour is used just where it should and nowhere else.

In a sector like the car industry where investments are always

very tight, this can represent an unacceptable level of

spending, yet the femtosecond laser can provide an economically

viable solution. By managing to modify the interior

of these sheets without affecting their structural integrity,

it is possible to separate their different zones by forming internal

barriers to introduce several colours simultaneously.

Alternatively, instead of processing the sheet to generate

barriers, arbitrary shapes can be generated and, since these

are illuminated on contact with light, they can serve as ornamental

motifs that change colour depending on the light

source used.


Controlled micro/nanotexturing of injection

moulds to generate patterns on their surface,

which are transmitted to the final piece in the

injection process. Different properties can thus be given to

plastic end pieces, ranging from optical effects (ornamentation)

to properties such as hydrophobicity or anti-fingerprint

effects (oleophobicity).

Iridisations produced by the micro/nanostructures generated in a

mould insert processed with femtosecond lasers.

These are just two examples that show the potential of

the femtosecond laser and its application in the automotive

sector. If we also consider that, once the initial

investment is made, the expense in fungibles, masks and

materials is almost nil, and that this technology respects

the environment without needing chemicals or abrasives

like other alternative technologies do, we believe that in

the future ultrashort pulse lasers will play a leading role

in manufacturing processes in which precision and quality

are the key to innovation.

Japanese cars surrender

to Spanish plastic fibre optic

communication systems

The standard designed by KDPOF passes the strict tests of

JASPAR, the organisation which includes companies such as

Toyota, Honda and Nissan.


Knowledge Development

To identify future challenges for the automotive sector

and look for possible solutions in order to standardise

them and mitigate the impact of these problems. This is

the goal of JASPAR (Japan Automotive Software Platform

and Architecture), the Japanese organisation that represents

more than 220 companies in the sector, among

which are the main car manufacturers and suppliers, such as

Toyota, Honda, Mazda and Nissan, among others.

And it is precisely this platform that has just given a great

boost to the Spanish company KDPOF (Knowledge Development

for Plastic Optical Fibres), by passing strict operational

performance tests with its patented communication

system for the transmission and receipt of information at

Gigabit speed.

With the KD1053 integrated circuit, the Spanish company

that was established in 2010 and just over two years

ago became the Ethernet standard for plastic fibre optic

according to the ETSI (European Telecommunications

Standards Institute) and the IEEE (Institute of Electrical

and Electronics Engineers), has taken a giant step

in the automotive sector, especially in relation to

the development of connected autonomous vehicles.

This type of vehicle, which all makes are

working on, requires an increase in sensors

and connected devices, which is generating

electromagnetic problems that hinder communications

and cause serious inefficiencies.

Plastic fibre optic systems come into play

here: their use is fundamental to facilitating

the connectivity of all of the car's digital elements.

"The KDPOF optical network solution

greatly improves the speed of automotive

light! by secpho 21

networks and has gone beyond the obsolete protocols of

previous networks," said Hideki Goto, head of the Next

Generation High-Speed Network working group at JAS-

PAR and a group manager at Toyota.

Goto points out that this technology is the "ideal" for future

network infrastructures in vehicles, as it enables wiring

that can be deployed along with electric wring, as it

does not conduct electricity and, therefore, meets the prerequisites

related to electromagnetic compatibility (EMC).

Exam passed

Among the numerous tests to which the plastic fibre optic

solution of the Spanish company has been subjected,

emission and immunity tests are included to guarantee

that it will not disturb the environment with electromagnetic

interference. Likewise, it has also passed different

extreme temperature tests, referring both to the plastic

fibre optic standard in the automotive sector and that of

optical connectors pursuant to the ISO 21111-4CD standard.

In addition, among the tests related to electromagnetic

compatibility, JASPAR has carried out tests on radiated

and conducted emissions (in order to check the disturbances

that voltage and current can cause).

Current injection (BCI) tests, and tests on immunity to radiated

radio frequency fields have also been performed,

as well as on electrostatic discharges (ESD) and transient


The KD1053 solution has met all standards with a considerable

margin. Thus, Hideki Goto is satisfied with the

results of this project, because the main objective of JAS-

PAR is "to generate an environment that allows the Japanese

automotive sector to cooperate and further boost


Already integrated in future models

This acknowledgment by the Japanese motor vehicle sector

is added to that of a giant, in this case a German multinational.

In just over a year, the battery management systems

of its hybrid and electric models will already have

KDPOF plastic optical fibre for all its communications.

The impulse of the plastic optical fibre from this Spanish

company is more than type approved and proof of this, as

Óscar Ciordia, its marketing manager, points out, is the

fact that they are also working with other OEMs (original

equipment manufacturers), for future launches, after

Smart glass

that adapts to solar radiation

Vehicle designers consider it an essential

requirement to ensure an

adequate level of comfort inside the

passenger compartment. For this

purpose, thermal and visual comfort

conditions are particularly relevant. A

clear example is the unpleasant situation

when getting into a vehicle that

has been parked in the sun for a few

hours; or also, the effect of glare in

low light conditions. The market provides

glass for cars that is designed as

a compromise between extreme climates,

but that is unable to regulate

light and heat intensity in particular


This problem can be solved thanks to

the implementation of a new generation

of intelligent glass able to automatically

adapt to weather conditions

and regulate the intensity of the solar

radiation that reaches the interior.

This glass, technically called "plasmochromic",

is based on the use of a new

technology that enables constant regulation

of the visible and thermal radiation

passing through the glass, after

the application of a small electrical


These two magnitudes (visible and

infrared light) directly affect energy

consumption inside the vehicle and

the comfort of the occupants. This

new plasmochromic technology is

based on the use of intelligent nanomaterials

that selectively filter the

intensity of incident radiation after

being interconnected with a sensor

system that constantly determines

solar radiation values, maximising

comfort and minimising energy expenditure.

It is thus possible to regulate

the intensity of thermal radiation

by letting the heat carried by the sun's

rays in winter pass through and rejecting

it in the summer without compromising

the transparency of the glass.

This functionality is an absolute novelty

in the field of smart window technologies,

considering that infrared radiation

accounts for 53% of the energy transmitted

by solar rays.

Researchers at the LEITAT Technological

Centre, in collaboration with Istituto

Italiano di Tecnologia (IIT), are working

on the development of this technology

in the framework of the SUNDANCING

project, with the support of the Regional

Government of Catalonia's Agency

for the Business Competitiveness (AC-

CIÓ). The objective is to develop interfacial

dynamic glass prototypes with IoT

digital control systems. In the not so

distant future, cars will have glass capable

of recording the changing physiological

demands of drivers in real time

and smartly adapting to prevent and reduce

distractions and accidents.

components for motor vehicles:

the solution in New Space?

The space industry is becoming an increasingly competitive

sector, requiring systems with better performance at a

lower cost. This is particularly applicable to small satellites

and what is now known as New Space. This trend has consequences

at all levels of the production chain, including

the selection, acquisition and verification of the electronic

components used.

The certified components available for space applications

are not able to meet the needs of current missions, either

because of their cost or because of their limited availability,

lack of new functionalities, degree of miniaturisation,

etc. This is especially true for optoelectronic devices for

which there is no space-qualified component, when photonic

technologies are a clear driver of the new generation

of space systems.

Optoelectronic devices (LEDs, photodetectors, fibre optics,

etc.) have not only begun to be used recurrently in space,

but also classic components (such as solar sensors, CMOS

cameras, etc.) are becoming key elements for success of

various instruments and missions.

There are well-known advantages to using these photonic

technologies in space, such as the limited generation of

noise, electromagnetic immunity, mass reduction, greater

bandwidth and great ability to multiplex signals, enabling a

high volume of data transmission, etc. Undoubtedly, all this

makes its use very attractive. However, we must first overcome

the lack of availability of these qualified components

for this sector.

ALTER TECHNOLOGY GROUP has developed extensive

experience and knowledge in the encapsulation

and verification of opto-electronic devices,

covering the full range of technologies and devices,

such as:

• Laser & LEDs 250 to 5000 nm

• Recipient modules (180 to 11000 nm)

• Amplifiers and optical modulators

• Switches and dividers

• Optocouplers and photodiodes

• Multimode and single mode optic fibres

• Liquid crystal devices

• Image sensors

• Optical transceivers


Likewise, electronic components designed for other industrial

applications, such as the car industry, are beginning

to show high levels of reliability when they are

produced in large volumes and when they are subject

to dedicated rating schemes (e.g. AEC Q), and their use

could be a solution to the problems described above for

the space sector. However, there is still a significant distance

between space requirements and the potential reliable

use of parts not designed for this sector.

The AEC ( was created in the nineties,

as a result of several discussions among leading automotive

manufacturers: DELCO Electronics, Chrysler,

light! by secpho 27

Ford, etc. Its impetus was mainly due to the difficulties they

faced in obtaining certified electronic parts to meet the

needs of their sector, with the aim of achieving a common

certification scheme. With these considerations in mind,

the AEC Q100 standard (Qualification test for integrated

circuits) was developed, which today involves more than

twenty recognised automotive equipment suppliers and

more than thirty electronic component manufacturers.

The qualification flow that was designed is robust and

covers the types of degradation mechanisms attributable

to components during a standard automotive application.

However, if we compare these requirements with the standards

used in Europe for space, the ESCC system (www., there are not only some differences

associated with the test flows and sample sizes used,

but also some key differential elements:

The "third party" function is missing to manage and

monitor the rating process. The ratings in the ECSS

system are maintained by ESA and several European

space agencies, while the AEC rating is conducted directly

by the component manufacturers themselves,

there is no external entity to review it.

After completing the first AEC qualification, validity

is indefinite with no periodic testing required, while

ESCC qualifications require a maintenance process

and the need to perform a significant number of periodic

tests, every two years.

The AEC system lacks detailed specifications for each

product, as defined and understood in other specification

systems (ESCC, MIL, etc.), which include detailed

conditions for the performance of each test,

failure criteria, etc.

In the automotive sector, manufacturers have a high

degree of freedom to change their processes and

perform requalification, which does not happen in

the space sector.

Batch concept: the degree of homogeneity and management

requirements are more relaxed, while batch

definition in the ESCC system is very strict, detailed

requirements are applicable to the use of raw materials:

the origin of wafers, encapsulated batches, manufacturing

and testing, etc.

Characterising anti-radiation behaviour, both response

Integrity in vacuum conditions and degassing characteristics.

The need to have broader operating temperature ranges,

integrity to thermal cycles, etc.

It does not consider the use of prohibited materials in

space; for example, pure tin, which in certain conditions

can produce tin filaments, a mechanism of failure

known to produce short circuits.

We must emphasise the importance of knowing all fundamental

failure modes that can be suffered by automotive

parts during a space mission, including all pertinent aspects

in the test plan, from a radiation test, to the verification

of degassing levels, or the possible presence of prohibited

materials, using appropriate inspection techniques: electrical

measurements, X-ray inspection, acoustic verification

(CSAM), electronic microscopy (SEM), EDAX, X-ray fluorescence,


It should be considered that activities on a component level

must be complemented by and connected with other actions

that influence the reliability of the final equipment, from the

design itself (introduction of redundancies, etc.), to the tests

carried out at higher levels of integration.

The added value of all these processes is based on adequate

engineering work, an in-depth knowledge of the technologies

to be evaluated, together with experience and access

to the necessary test methods and inspection techniques.

Once the batch has passed the planned research and test

activities, it is deemed trustworthy for use in the application.

On the other hand, the normal way to acquire parts within

the automotive sector is with the use of a PPAP (Production

Part Approval Process). The PPAP is a valuable tool for trusting

component suppliers and their production processes,

but it requires orders of large quantities of parts, larger than

those needed in the space sector, even considering the new

needs of the mega-constellation of satellites.

(Top image) Summary of the measurement bank.

(Image below) Detail of an internal visual inspection of a semiconductor


In line with these considerations, the AEC qualified automotive

components are clearly not a direct replacement for

the qualified components for use in space and do not fully

meet the sector's demands; however, they remain of high

interest and have great potential for use in space, designing

protocols that complement this difference and enabling the

level of confidence required by the sector to be reached.

ensures excellence

in laser welding

New Infrared Technologies (NIT), in collaboration with the

AIMEN Technology Centre, has developed the I3LASWELD

system for the inline quality control of laser welding processes,

capable of detecting defects in weld seams in real time

and identifying defective parts.

The I3LASWELD system (Inline Infrared Imaging Laser Welding

QA) is based on a high speed infrared camera (1 kHz)

manufactured by NIT, opto-mechanically coupled to the laser

optics, which continuously monitors the geometry of the

melt-pool. These infrared images of the melt-pool, acquired

coaxially, are processed in real time using powerful algorithms

based on neural networks, which provide information

about the areas where the defects are concentrated and

thus enable an evaluation of final quality (OK / NOK).

The I3LASWELD system is compatible with both fixed and

remote welding laser optics, and can be trained to detect

multiple defects in different configurations, process types

(transparency, butt or edge), sheet materials and thicknesses.

As training is based on images of real processes, in which

the defects to be detected have been forced in a production

scenario, I3LASWELD provides very high defect detection

rates with a success rate of more than 99%. Some examples

of defects that I3LASWELD is able to detect very accurately

are: lack of penetration, lack of fusion (false friend), excessive

throat depth and absence of bead (discontinuities, pores,

holes), among others.

I3LASWELD has been successfully validated in a collaborative

project with VOLVO, in which quality control of

transparency welds between steel sheets (0.75 mm +

0.70 mm) was carried out to ensure that the process met

the required standards regarding both depth of the weld

throat and internal width of the joint.

Currently, NIT and AIMEN are implementing the I3LAS-

WELD system in a GESTAMP production cell, at its

Abrera plant, to detect defects in welds on-the-fly using

a remote welding optical scanner, aiming to control the

quality of more than 10,000 weld beads per production

shift. The interconnection of I3LASWELD with the production

quality control system implemented in the process

cell will enable immediate performance metrics to be

obtained, providing very accurate and valuable information

to production engineers, in real time.

Smart manufacturing

becomes portable

Portability, reliability and simplicity: the three attributes

that new technologies have been providing to

engineers and manufacturers in their daily work. Now,

these technologies are doing the same thing in the

field of metrology, inspection and quality control.

It used to be common to see technicians working in

closed metrology laboratories, sealed and away from

the workshop. That is now ancient history. The new

portable laser 3D scanners and portable optical coordinate

measuring machines (CMM) are able to provide

the most reliable metrology data for inspection

and quality control anywhere, and in the working conditions

of any workshop.

In metrology, the great innovation has been the incorporation

of coordinate optical measurement devices

and fully portable 3D laser scanners. Extremely

manageable and comfortable to use, they offer precision

metrology without being affected by the environment.

The part to be measured can be in movement,

because the scanner or CMM can move during measurement.

It does not matter if there are vibrations,

changes in temperature, or light. These characteristics

mean that measurements can be made in the workshop

itself, on the production line, at the customer's

house or outdoors. It doesn't matter. The accuracy of

the measurements will not be altered in any case.

The new range of fully portable optical metrology systems from

Creaform available from AsorCAD Engineering.

The new generation of portable CMM scanners and systems

offers five major advances that make them the ultimate

solution for metrologists and manufacturers around

the world:

Dynamic references that turn the scanner or the

CMM system into devices that are unaffected by

involuntary movements or the vibrations and disturbances

that are typical of a workshop.

Automatic alignment that eliminates the errors inherent

in the manual alignment process.

Smart measurement, a process that optimises data

and ensures the highest level of accuracy.

Easy calibration in situ that can be performed by a

non-specialised operator in less than 5 minutes.

Wireless, with strong, low-cost targets, which reduces

the complexity of the measurement process, maintaining

its accuracy.

These five advances provide unquestionable business benefits:

faster measurements that speed up time to market and

ensure quality in each phase of the product's life cycle management.

The need for fast, reliable and portable measurement systems

is growing in industrial development and production,

especially in metrology, quality control and inspection.

The greatest impact is being seen in the most common type

of quality control: the inspection of the parts produced. Portable

optical technologies are allowing companies to integrate

quality control and inspection of parts into the same

production process, saving both time and money.

In addition to the inspection of the parts produced, the new

portable 3D scanners and portable CMM optical systems are

used in an increasingly wide variety of quality control applications,

in almost all types of industry.

Cutting-edge solutions

in thermography, at the service

of the Automotive Industry

The automotive industry is one of the most important economic

sectors in the world. Quality standards are increasingly

high, along with the demand for production, which is

why many car manufacturers use thermal imaging cameras

for quality control.

Thermography is a fundamental tool for inspecting, checking

and improving processes. In addition to being reliable tools

which don’t need contact, thermographic cameras provide

temperature measurements of an entire area, instead of

specific points. Using the temperature map and using image

processing algorithms it is possible to determine error zones

Thermal radiation is present in all processes,

so analysing and recording it is

of key importance.

due to lack of material input, welding points that are burnt

or too cold, etc.

In the automotive sector, thermography can be used in multiple

applications, some of which are described below:

light! by secpho 39



Process and quality control

Process control involves measuring the temperature

and identifying the shape of certain products in a production

line, so that they conform to specifications.

Artificial vision can detect a production problem, but

not thermal irregularities. Indeed, thermography provides

much more information to production specialists

and decision makers, adding a new dimension to

computer vision.

Many automobile manufacturers use thermographic

cameras for quality control. New vehicles undergo

a multitude of tests for this purpose. Typical applications

include inspection of rear window heating,

heated seats, exhaust covers, air conditioning outlets,

etc. Thermography is essential in durability and

validation tests.

Hot forming stamping

and forging

The hot forming process is based on combining a

deformation operation of the base material (sheet

or billet) at high temperature with subsequent

quenching treatment. While hot, the material is

more ductile and the piece is deformed with smaller

forces. Subsequent rapid cooling gives it its highstrength

martensitic structure. The microstructure

and final properties of the manufactured part are

strictly linked to a good control of the temperatures,

times and deformations applied.

Large temperature differences in the part or in the

die during the process lead to the appearance of

non-homogeneous deformations that can put the

manufactured part out of tolerance. To avoid this,

the thermal monitoring of hot forming cycles is required

to evaluate the evolution of the temperature

in the part before and after deformation, as well as

the correct cooling of the die.

Quality control for car


A reduction in the failure rate of electronic vehicle

components is essential. The only way to guarantee

this reduction is to check each component individually

thereby offering 100% guaranteed quality control.

Thermography allows electronic component

manufacturers to detect hot spots, which is an indication

of defective products.

Additive manufacturing

Also known as 3D printing, it allows you to create

pieces directly from a digital model without the need

for traditional subtractive machining tools and with

minimal geometric limitations. Heat is an integral part

of the additive manufacturing process and needs to

be monitored to detect phenomena that have a direct

effect on both the dimensional and mechanical

quality and performance of the final product. The

diagnosis of thermal stress or distortions using typical

contact sensors such as thermocouples, RTDs

or thermistors, is complicated or even impossible.

Thermographic cameras help to study the process

and its thermal properties, correlating temperatures

measured during the process with quality parameters

for the finished product. With the help of thermography

it is possible to identify porosity, delamination,

retraction, poor surface finish or dimensional defects.

Comparison of thermal dissipation between electronic circuits

Thermal treatments for monitoring the

manufacture of metal parts

Heat treatment is used to alter the chemical and

physical properties of manufactured metal parts, and

is capable of monitoring their hardness or lack thereof.

A case in which thermography can be really useful is

in the casting processes of steel mills, both in continuous

and mould casting. For iron part manufacturers

in the automotive sector, knowledge of the temperature

of the iron in the casting furnace is fundamental,

as the filling temperature of the mould must be very

precise to achieve the desired physical properties in

the part.

Currently, temperature control in this type of process

is carried out with probes or rods introduced into the

liquid metal bath, which have considerable thermal

inertia, and can overheat when the process starts

from a cold state. So the temperature obtained differs

from that of emptying, which happens 5 to 10

minutes later. However, with thermographic cameras

we obtain instant measurements during the pouring

process, which enables us to operate with a much

greater reaction margin and forego the need for


Measurement by thermography is not only capable

of measuring up to 1700°C (the pouring point for

certain metals), but also of making this measurement

as safely as possible, at a distance and without needing

to intervene in the process. Repeatability and

measurement quality is also high.

In addition, with a thermography system it is possible

to add functionalities, such as detecting in real

time when the slag appears in the steel stream in

pot filling, to stop it before it falls from the bucket.

A distinction is made by emissivity of the slag against

steel, signalling the slag with red isotherm.

oven. (Bottom image) Measurement by thermography.

bcb has developed a series of solutions aimed at the process

control, traceability and quality management of the

manufactured product. bcbMonitor® is a family of products

that integrates multiple combinations of thermographic

sensors, image management software and additional

elements on a single platform, to build a complete

thermographic monitoring solution adapted to the needs

of each particular application. It is also possible to define

Developments demanded

by the automotive industry

The automotive sector faces the most disruptive changes of

the last few decades. Changes that affect the car itself, including

weight reduction by the use of innovative materials

and multi-material structures. And changes that affect the

factory of the future, promoted by the incorporation of new

manufacturing technologies such as collaborative robotics,

additive manufacturing and the digitisation of industrial


Since it was established, AIMEN Technology Centre has

been collaborating with the automotive industry in the provision

of innovative solutions. Currently there are several

initiatives involving photonic technologies that the Centre

is developing in collaboration with this sector:


In the field of composite materials and multi-material structures

we can highlight the European initiative entitled Com-

Munion, led by AIMEN, where photonics play an important

role in applications related to the monitoring and control of

processes and the preparation of surfaces by laser texturing.

The objective of ComMunion is to develop a novel solution

for manufacturing multi-material metal/carbon fibre thermoplastic

composite 3D components in a productive and

cost-efficient way for the whole value chain of the automotive

industry. The system developed within the framework

of the project will be implemented in Autotech Engineering,

a project partner, where the new hybrid metal-composite

components will be manufactured and the novel system will

be tested.


Additive manufacturing of both polymer and metal components

are the focus of much of the Centre's current research.

An example is INTEGRADDE; a European initiative

also led by AIMEN, which will revolutionise 3D printing of

metal components in the European industry.

INTEGRADDE will develop a strategy of continuous and

integral control of additive manufacturing processes, from

product design to final verification.

Meanwhile, in the field of laser microprocessing, the

PHENOmenon initiative will develop new technology for

manufacturing optics and holographic products in an economical

and customised way for high-efficiency lighting,

safety, aerospace applications or 3D visualisation.

The project will focus on the additive manufacturing, based

on direct energy deposition processes, of medium/large

metal parts for multiple industrial applications, including the

automotive sector.

The Slovenian partner CORDA will focus on the repair of

stamping moulds used in the manufacture of automotive

components using LMD-powder.


Another ongoing project within the field of laser technology

application, and in particular the shaping of the laser

beam, is CUSTODIAN, a European initiative that seeks to

develop a laser device which is adaptable to each application

in order to achieve faultless processing. It is based on a

methodology that includes determining the optimal thermal

cycle for each material/application, developing a photonic

system that emits a reconfigurable laser beam that enables

reproduction of the optimal thermal cycle and the design of

a real-time monitoring and control system. This will enable

any laser process to be designed exactly in accordance with

the thermal transformation required by the material, which

will benefit productivity, quality and cost reduction.

Holograms can be defined as photographs of the transmission

of light itself. Using lasers, this light can be reconstructed

making it appear to represent a three-dimensional

object. In addition to 3D images, holographic

technology can be used to create ultra-thin, ultra-light

optical lenses and systems with a quality far superior

to that of conventional glass lenses. It can also provide

unique characteristics, thanks to the precise control of

light: anti-fog vision, extreme concentration of light, or

absence of chromatic aberrations and defects. All this

opens the door to ultra-miniaturised devices for surveillance,

medicine, solar cell concentrators or more efficient

forms of lighting. PSA France, one of the project partners,

is studying the possibility of using the technologies developed

within the framework of this initiative to design

new methods of interaction between vehicle and driver.

In addition to these projects, AIMEN currently maintains

strategic research alliances with large companies in the

automotive sector. This is the case of the JOINTS4.0 initiative,

set up with GKN Driveline Vigo, through which

new technologies are being developed for the sustainable

and high-performance manufacture of automotive transmission

components. Likewise, DIGI4AUT, the alliance

with the COPO Group, is pursuing the development and

implementation of digital technologies to establish a new

advanced, agile and flexible factory concept, adapted to

the manufacture of components for the interior of vehicles.

Innovative laser technology

in electric car manufacturing


Compared to petrol and diesel powered vehicles,

electric car technology (emobility) is in its infancy

(for example, in performance and range) and is,

therefore, technically much more dynamic. This

means that the metal parts and the metals themselves

are being applied in new ways and/or being

pushed to new limits. But, at the same time, vehicle

manufacturers and lower-tier suppliers are only

willing to adopt manufacturing technologies that

are scalable and highly profitable. All these reasons

favour lasers over many other methods for welding,

cutting, hardening, wire welding and other applications,

since lasers offer non-contact, wear-free,

consistent and high-speed processing. However,

the demands for delivery of advanced functionality

components often exceed conventional laser processing.

In this article, we analyse two innovations

in laser welding specifically aimed at automotive

electric mobility components.

A key stage in the production of lithium ion batteries used

in electric vehicles is the welding of battery boxes. It is essential

that this weld is totally hermetic during the entire

useful life of the component. In particular, this seal must

prevent moisture infiltration because water reacts strongly

with lithium, creating gas and pressure that could destroy

the device. In addition, the welding process itself should not

cause splashing, since metal particles (as well as moisture)

can create internal leakage currents that could short-circuit

the battery. Finally, and from the mechanical point of

view, the welding must be strong enough to withstand the

vibrations from the road surface, or even the shock from a


The sealing of the aluminium battery box has traditionally

been done with laser conduction welding because the

battery walls are thin (



has shown that the proper approach to the problem is to use

a Gaussian central distribution point, surrounded by another

concentric ring of laser light.

This unusual configuration is achieved using the adjustable

ring mode fibre laser (FL-ARM) from Coherent’s HighLight

series. The beam transport fibre of this laser includes a conventional

circular core surrounded by another fibre core of

annular cross section.

Coherent supplies FL-ARM systems with output powers

ranging from 2.5 kW to 10 kW. The power in the centre and

the ring can be adjusted independently, on demand, within a

range of 1% to 100% of the nominal maximum output. The

core and ring beams can even be independently modulated,

at repetition rates of up to 5 kHz.

With this configuration, there is a virtually limitless number

of possible combinations in terms of the power ratio of the

inner beam to the outer beam. However, all of these can

be broadly grouped in the configurations shown in Figure 1.

These basic patterns can be varied to offer a wide range of

processing characteristics to optimally serve a diverse set of


For fibre laser welding of aluminium, one challenge has

been that the material has a relatively low absorption in

the near infrared. Small unpredictable variations in absorption

cause the depth of penetration to vary, resulting in

uneven welding.

To address this, and to provide sufficiently precise control

as required by the key-hole welding of the aluminium battery

boxes, the FL-ARM beam is configured with power in

both the centre and the ring. Using this particular power

configuration, the leading edge of the ring beam raises the

temperature of the aluminium enough to increase its absorption

at the laser wavelength. Subsequently, the laser

beam of the nucleus creates the key-hole, which is now

very stable due to preheating. The back edge of the ring

keeps the fusion pool open long enough to allow the gas

to escape. Because the key-hole is stable and the material

does not solidify so quickly, the whole process is more

consistent and the process window is larger. The final result

is a uniform and constant penetration of the material

and welds of higher quality, without splashes or porosity.

Another demanding challenge in the production of the electric

car is the welding of copper coil pins in the stator of an

electric motor. These rigid pins (called 'hairpins' due to their

'u' shape) replace the copper wire windings that are traditionally

used in an electric motor. Because they are much

stiffer than cables, their orientation in the motor can be

controlled more precisely, which ultimately results in better

heat management and higher motor performance.

In the assembly process, the individual pins are first loaded

into the stator slots. Then, the ends of the adjacent pins

are welded together to electrically connect them. When the

entire engine is finished, all the pins will act as a single long,

twisted conductor, like the windings of a conventional electric


The two key imperatives of this process are that the weld

maintains the correct mechanical alignment of the pins and

that it does not produce any defect (inclusions). The alignment

of the pins is important because the exact shape of

the winding directly affects the efficiency of the motor. Defects

must be avoided because they increase the resistance

of the final winding, which reduces its electrical efficiency

and can also decrease the mechanical strength of the assembly.

Coherent | ROFIN has developed a method based on fibre

laser to perform pin welding that achieves all these objectives.

The first key element of this process, which is based

on a standard fibre laser from the HighLightTM series, involves

the use of so-called 'beam oscillation'. In this case,

the size of the beam focused on the work surface is deliberately

smaller than the total area to be welded. However,

the position of the place is quickly scanned (oscillation) to

cover the entire area.

As with the FL-ARM laser, the advantage of beam oscillation

is that it allows more precise control over the temperature

dynamics of the fusion pool. By moving the beam

quickly and repeatedly over the part, and not allowing it to

stop anywhere, it essentially preheats the part in a very controlled

manner, instead of discharging all the power at once.

All this stabilizes the melting bath, reducing splashes, defects

and the porosity of the weld compared to traditional

methods of laser welding.

5000 of 1.6 mm thickness that shows deep penetration without

pores or splashes. Figure 3. Longitudinal cross section along a 20 mm

weld bead showing uniform penetration. Figure 4. Unprocessed copper


Coherent | ROFIN also offers practical tools related to processes

that improve laser welding results in a production

environment. The company can supply a laser welding subsystem

that includes an artificial vision system to control the

relative position of the focused laser beam and the tips of

the pins.

You can watch videos of these processes at https://www.

In conclusion, developing and implementing a successful laser

production process involves exploring a portfolio of parameters,

configurations and techniques that will ultimately

offer the best welding results. Coherent | ROFIN has both

the experience and the resources to perform the development

work required to identify these various elements. In

addition, Coherent | ROFIN can integrate all the required

functionality (beam oscillation, FL-ARM adjustable mode

profiles, process monitoring, etc.) into a single subsystem,

which is controlled through a graphical user interface (GUI).

The ability to acquire a complete and integrated laser welding

system, instead of using part assembly, eliminates much

of the uncertainty that can occur when an integrator assembles

a system and finds that several elements do not work

together successfully.

Disruptive technology for the manufacture

of the vehicle of the future

Globally, China has clearly positioned itself in the lead regarding

the volume of production of electric cars, with a

market share of 2.2% and annual production of close to

600,000 units; triple that of the United States. The number

of electric vehicles on the road has already exceeded

3 million, 40% of them in China.

16 countries, among which are the 7 largest economies

in the world - the United States, China, Japan, Germany,

the United Kingdom, India and France - currently participate

in the EVI - Electric Vehicles Initiative, the mission

of which is to accelerate the development of electric

vehicles. The objective of the EV30@30 campaign is to

achieve a market share of at least 30% of all vehicles sold

by 2030, considering that the electrification of transport

will help facilitate the transition to a "clean" energy system.

According to the EV30@30 scenario, around 220

million electric vehicles would be on our roads by 2030.

Measures adopted by different governments include measures

to promote R&D and improve productive processes

and capacities, facilitating the adoption of technologies that

contribute to electromobility.

The percentage of electrical and electronic components in an

electric vehicle is much higher than in a car with an internal

combustion engine - a not insignificant figure: motors, batteries,

wiring, complex electronic systems with sensors and

actuators... And each component and each element within

these components needs to be mounted with the greatest

mechanical and electrical reliability, with process qualities

and speeds unprecedented in some traditional technologies.

Laser technologies have become an essential tool in numerous

manufacturing processes in the automotive industry,

offering product and process qualities that until a few years

ago were unattainable using conventional technologies. In

the field of welding, lasers have replaced resistance welding,

arc welding, ultrasonic welding and other traditional joining

processes in numerous applications.

But lasers also have their limitations. One of these limitations

is that traditional industrial lasers operate at infrared

wavelengths, for which the absorptivity of non-ferrous metals,

and especially copper, is very small. It was necessary to

light! by secpho 51


develop a laser with a wavelength for which said absorptivity

was sufficient to guarantee quality welding, with a

process speed suitable for high manufacturing volumes.

And that wavelength is in the range of 450nm - blue light.

Copper absorbs less than 5% of the radiation emitted by

an infrared laser. This low absorption is not only a problem

in terms of energy efficiency, but the excess energy

required to start laser welding makes part of the metal

evaporate from the weld pool (which absorbs more energy

than the base metal), generating bubbles that give rise to

splashes and pores in the weld. The blue wavelength has

absorption levels more than ten times higher than infrared

and, no less important, the energy required to maintain

the weld is similar to that required to start it. In practical

terms, this translates into splash and pore-free welding, a

stable process that is much faster than can be achieved

with infrared lasers.

Examples of blue laser welding

with different thicknesses of copper.

The advantages of the blue wavelength had been known

for decades, but nobody had managed to develop a

high-power industrial laser at this wavelength. In 2017,

NUBURU® launched its first high-performance blue laser,

the AO-150 (150 W), which was followed in December

2018 by the AO-500 (500 W), with new models in development.

The AO® series lasers combine the output of dozens of

gallium nitride (GaN) laser diodes in a single beam and

couple that beam to an optical fibre, 200 μm in the case

of the AO-150, and 400 μm for the AO-500, with a highly

symmetrical and high-brightness beam. This high energy

density makes the lasers developed by NUBURU® the

most efficient. The stability of these lasers and their large

process windows enable pore and splash-free welding in

the three available operating modes: conduction, transition

and keyhole.

Among the multiple applications of the blue laser in the

automotive industry, it is worth highlighting a particularly

critical one: the welding of the layers of thin sheets of

copper used in the electrodes of Ion-Lithium batteries. The

greater the number of sheets, the greater the capacity for

energy storage. The use of blue laser in these welds allows

a greater concentration of sheets, welded without pores

or splashes and with very short welding times, and subsequent

economic savings. Blue lasers weld copper joints

with flexibility, speed, and unrivalled quality, which makes

them a very attractive option to improve productivity in

vehicle component manufacturing.

The tendency towards the greater concentration of electrical

and electronic elements in increasingly reduced

spaces requires a perfect weld seal quality, without pores

that degrade the conductivity of the joint, impurities, or

projections that can cause short circuits. The advantages

of blue laser over other technologies such as infrared laser

or ultrasonic welding are evident, and rapid implementation

of this technology is expected in the next few years in

the manufacture of automotive components.

The role of the ALBA Synchrotron

in relation to challenges

in the car industry

The ALBA Synchrotron is the only synchrotron light source that exists in Spain; a light that is different due to its high brightness

and intensity. It is for this reason that measurements with synchrotron light require less time, are more accurate than laboratory-based

methods and, in general, are not destructive. This makes it suitable for observing the structure and properties of a

great number of materials, including those used in vehicles, on a micro and nanoscopic scale.

The ALBA Synchrotron can be of great help in relation to the challenges facing the automotive industry, such as how to achieve:

More durable batteries for hybrid and

electric vehicles

Batteries with greater storage capacity plus rapid and efficient

energy release are a major challenge for the automotive

sector. Improving the different materials that make up

battery components (anodes, cathodes, electrolytes, etc.) is

essential for increasing their performance. The ALBA Synchrotron

is a great specialist in the study of batteries, both

in-situ and in the different phases of the battery's useful life

and during the charging process.

New stronger yet more lightweight

materials, such as steel or plastics

Making car materials more lightweight helps reduce fuel consumption;

they should also be stronger to improve the impact

of deformation and increase safety. The properties of these

materials are strongly correlated to their structure, so the synchrotron

techniques that characterise micro and nanoscopic

structure are of the utmost importance for their improvement.

More efficient catalytic converters to

reduce the emission of pollutants

The exhaust pipe catalytic converters on vehicles lose efficiency as

they age due to sintering (aggregation of catalytic nanoparticles),

which causes a loss of active surface. Synchrotron techniques enable

the study of the mechanism and behaviour of catalytic materials

during activation and while catalytic reactions take place in

the car, which enables us to improve their properties and efficiency,

while making them more durable.

Materials for vehicles

driven by hydrogen

The success of this type of vehicle depends to a

large extent on the ability to obtain lightweight,

compact and safe hydrogen storage devices for

adequate amounts of hydrogen. The Synchrotron

has studied different materials for such purposes

with the aim of finding solutions applicable on an

industrial scale.

The information obtained in a synchrotron

installation helps to develop new

processes, characterise material in situ,

improve its properties and reduce costs.

synchrotron could be helpful for your
