Materials and surfaces
Surface roughness measurement for sensitive surfaces –
fast and precise determination in micrometres!
Quick and targeted measurement
of surface roughness plays a key
role in industries subject to stringent
hygiene regulations, such as medical
technology and the food industry:
these days there is growing recognition
that the surface quality, and
thus the determination of the surface
roughness, is absolutely essential for
establishing the corrosion resistance
characteristics of a material.
An extremely rough and badly
ground surface on mat. 1.4404 can
result in poorer corrosion resistance
characteristics than a surface that
is properly ground and smooth, or
electropolished on mat. 1.4301!
This is why, besides the material
itself, the choice of surface is one
of the key selection criteria when
it comes to ensuring the correct
corrosion resistance characteristics.
Your surface quality check should
include an analysis and confirmation
of material surface roughness!
The surface is precisely scanned
along a length of up to 12.5 mm.
This allows a range of average
roughness values to be measured:
arithmetical mean roughness Ra,
square mean roughness Rq, mean
peak-to-valley height Rz, etc.

Quality assurance through surface roughness
measurement
Mobile material
analysis
In industry and the craft trades,
there is growing interest in reliable
information regarding the quality of
materials. Lives may depend on the
right material quality being used:
the consequences of inadvertently
selecting the wrong material, say
for a facade fastening, could be
disastrous...
A new technology from the USA,
developed for NASA (tried and
tested in the Mars robot!) and using
x-rays, now provides reliable
data. The “Nitron” device quickly
and precisely determines chemical
elements in metal alloys (in the
titanium-uranium element range)
and supplies the relevant data at
the touch of a button.
Sheet metals, wires, tubes and also
welded structures incl. the weld
seams are tested. The standard elements
for the test are: Ti, V, Cr, Mn,
Fe, Co, Ni, Cu, Zn, Zr, Nb, Mo, Hf,
Ta, W, Re, Pb, Bi, Pd, Ag, Sn.
It does not analyze any other elements
present, such as Alu, C, P, S
and Si.
It goes without saying that purchasing
such a device is extremely
costly. We invested in this device
for quality assurance purposes, in
particular with regard to our incoming
goods inspection, in order to
establish unambiguous identification
of the new Lean Duplex Steel.
Then we had the idea of leasing the
test device as a “mobile task force”.
The temporary leasing of our device
complete with operator offers our
customers a low-cost alternative,
should procurement of such a device
not prove economically viable.
Numerous companies across East
Westphalia have already taken advantage
of this simple alloy analysis
/ positive material identification
option, which is simple to
order either by phone or
e-mail. Please contact us
for further details!
We test materials for their alloy
components using an X-ray
fluorescence device.
