3:10pm B1-2-6 The influence of deposited surface structures on mechanical properties, M.C. Fuchs (marcus.fuchs@s2003.tuchemnitz.de), N. Schwarzer, Saxonian Institute of Surface Mechanics, Germany It is well known and logical that certain deposition parameters have a great effect on surface structures like surface roughness, interface roughness, porosity, intergrain interaction, homogeneity or grain size. However, it is almost impossible to find deposition parameters or even ranges of them for processing of specific surface structures which are generally valid for all deposition techniques as there is a broad variety of them. Even with the same deposition technique only slight changes in the geometry of the deposition configuration can cause big differences. But such surface structures can influence the apparent mechanical properties of surface materials due to the method which is usually applied for determining them. Preferably one uses contact experiments like load-displacement sensing indentation measurements with subsequent classic Oliver & Pharr analysis, scratch or highly sophisticated (physicalized [1]) tribological tests. Consequently, deposition parameters can effect the resulting mechanical material properties like yield strength Y, hardness H and elastic modulus E. Such effects should be taken into account during the parameter identification analyzes of mechanical material properties. Because they are not only important for quantification of the mechanical behavior of coatings, but also important indicators (e.g. H in relation to E) for the tribological performance (e.g. wear, friction) of tribological coatings. Nevertheless, it is not possible to derive such effects on the mechanical material properties solely from the deposition parameters as a result of the dynamic nature of any deposition process. Hence, it is very important to know the resulting coating structure of a deposition process. It should be measured after processing when the surface is in a static state. Such effects and their partially dramatic influence on the resulting mechanical properties will be demonstrated on the examples of ta-C and nano-composite coatings. For example it will be shown how simple roughness can lead to false apparent ultra-hardness results. In the same context it is demonstrated how inadequate or incomplete analyzes features and theoretical approaches can directly lead to severely flawed conclusion about the actual coatings stability and reliability. Last but not least, of course, it will be shown how it is been done correctly. [1] Schwarzer et al.: “Optimization of the Scratch Test for Specific Coating Designs”. SCT, accepted 2011. 3:30pm B1-2-7 High Rate Magnetron Sputtering of Chromium Coatings for Tribological Applications, K. Nygren (kristian.nygren@mkem.uu.se), Uppsala University, Angstrom Laboratory, Sweden, M. Samuelsson, Linköping University, Sweden, Å. Kassman- Rudolphi, Uppsala University, Angstrom Laboratory, Sweden, U. Helmersson, Linköping University, Sweden, U. Jansson, Uppsala University, Angstrom Laboratory, Sweden Increasing demands on tribological performance drive the development of innovative coating materials and deposition methods. Recent studies of reactively sputtered chromium carbide films show promising results with regards to coefficients of friction [1], and these coatings may be suitable for commercial purposes. However, transfer of a process to industrial conditions poses challenges, such as growing the films at significantly higher deposition rates. While this is known to influence the microstructure and phase content, which in turn determine the tribological performance, the implications for the Cr-C system are not fully understood. The objective of the present study is to investigate chromium carbide films deposited by direct current magnetron sputtering (DCMS) and high power impulse magnetron sputtering (HiPIMS) in an industrial deposition system, at growth rates up to 500 nm/min. While DCMS offers a higher deposition rate, HiPIMS is known to result in well-adherent, dense, and smooth coatings. Microstructural changes are expected as well as modified tribological and mechanical properties owing to the high deposition rate. Cr-C coatings were synthesized by sputtering of a Cr target in an Ar/C2H2 atmosphere. XRD shows an X-ray amorphous Cr-C phase, in contrast to the nanocrystalline structure usually reported [2-3]. For DC sputtered coatings, XPS reveals a C-C phase which increases according to the phase diagram for Cr-C. The coatings produced by HiPIMS feature a meta-stable, supersaturated Cr-C phase, with a higher C content than predicted for the thermodynamically stable phase Cr3C2. Coefficients of friction were obtained from dry-sliding experiments (typically 0.35 – 0.50 for 34 – 0 % C-C), and the values confirm a dependence on phase fractions of C-C and C-Cr. Regarding the mechanical properties, coatings deposited by DCMS have a hardness of 14±1 to 18±1 GPa (51 to 17 at.% C), while coatings deposited by HiPIMS have a hardness of 7±3 GPa to 14±4 GPa (59 to 26 at.% C). Unexpectedly, the coatings deposited by HiPIMS are softer than the ones deposited by DCMS, and this difference may be due to a different grain size or phase content. SEM cross-sections indicate deep Cr implantation in the substrate, which is known to improve adhesion. Further Monday Afternoon, April 23, 2012 10 results will be presented for a wide compositional range, and compared to literature.

Bobzin, N. Bagcivan, S. Theiss, R. Weiß (weiss@iot.rwth-aachen.de), Surface Engineering Institute - RWTH Aachen University, Germany, U. Depner, T. Troßmann, J. Ellermeier, M. Oechsner, Institute for Materials Technology - TU Darmstadt, Germany In many industrial applications components are subjected to mechanical load, while being exposed to corrosive environments. In order to cope with the resulting tribo-corrosion, both corrosion and wear resistant steels are often resorted to. Since those materials are expensive and often difficult to machine, the development of protective thin films deposited on less expensive and easily machinable materials, is of high interest. Due to their chemical stability and high tightness, diamond-like carbon (DLC) coatings deposited via physical vapor deposition (PVD) seem to be appropriate to offer corrosion protection in addition to their well-established wear resistance. This paper deals with the development of DLC multilayer coatings consisting of alternating a-C and chromium based layers and an a-C:H top layer. The coatings were deposited on low-alloy steel (AISI 4140) using reactive magnetron sputter ion plating (MSIP) technology to investigate the possibility of improving the properties concerning tribocorrosion. The mechanical and tribological properties of the top layer were analyzed depending on the ethine gas flow. Furthermore, the influence of different transitions from the a-C to the chromium based layers on the fatigue strength was investigated. The applicability of the DLC coatings in corrosive environments was proved using potentiodynamic polarization tests in artificial seawater: While the open circuit potential increases significantly from -400 mVH (AISI 4140) to about 300 mVH, current density remains below 0,001 mAcm -2 up to the maximum load of 1200 mVH (AISI 4140: 100 mAcm -2 ). The tribological analyses regarding continuous sliding abrasion using a pin-on-disk tribometer show that the developed DLC coatings lead to very low wear rates in aqueous environment and in contact with an Al2O3 counterpart, nearly independent of the ethine gas flow. Moreover, investigations in an impact tribometer with maximum initial Hertzian stress of about 10 GPa show that pure metallic chromium layers with a soft transition to the a-C layers improve the fatigue strength of the compound. Thus, even after 10 6 impacts the coatings were proved to be still impenetrable for an electrolyte that could lead to corrosion of the substrate. 4:10pm B1-2-9 Integration of the Larco ® -technology for ta-C-coatings in an industrial hard material batch system, M. Holzherr (katrin.wagner@vtd.de), M. Falz, T. Schmidt, VTD Vakuumtechnik Dresden GmbH, Germany, H.-J. Scheibe, M. Leonhardt, C.-F. Meyer, Fraunhofer-Institut für Werkstoff- und Strahltechnik, IWS, Germany DLC (diamond like carbon) thin film depositions are carried out in a wide range of CVD- and PVD technologies. Main applications are: tribologically stressed machine components as well as wear protection of tools. As a matter of fact, it could be verified that the hydrogen free DLC-coatings result in advanced thin film properties such as higher hardness which is caused by a higher sp 3 -bonding content. Therefore evaporation of solid graphite by PVD-technologies has been of considerable advantages. Especially the vacuum arc evaporation technique stands out for a very high degree of single and multiple ionised carbon atoms with increased energy necessary for condensation in the dense tetragonal amorphous diamondlike carbon film structure (ta-C). Beside low friction also super hard coatings can be deposited by means of that technology. A commercial hard material coating system has been equipped with a laser arc module (LAM) for the deposition of hydrogen-free ta-C-films. For industrial applications it was necessary to increase deposition rates. Therefore arc pulse current and pulse frequency were varied form 800 A to 1.600 A and 150 Hz to 300 Hz, respectively. The carbon plasma during deposition process were examined by optical emission spectroscopy (OES) and Langmuir probe and effect on plasma parameters of the thin film properties will be shown. The influence of the deposition rate on thin film properties is caused by thermal effects. One limitation is a maximal deposition temperature of about 150 °C in order to avoid the graphite film structure which results in reduction of hardness finally. The thin film depositions were carried out on samples of circular blanks and carbide drills. Hardness, adhesion and elastic force module are the first criteria for evaluating the quality of the deposited ta-C- films. As real
application tests the ta-C coated drills were used to machine an abrasive AlSi-alloy with high Si-content. 4:30pm B1-2-10 Ion-assisted PVD growth of carbon-transition metal nanocomposite thin films, G. Abrasonis (g.abrasonis@hzdr.de), Helmholtz-Zentrum Dresden-Rossendorf, Germany INVITED Nanostructures dramatically influence materials properties due to size, shape and interface effects. Thus the control over the structure at the nanoscale is a key issue in nanomaterials science. The interaction range of hyperthermal ions with solid surface is confined to some nanometers. Therefore hyperthermal ion assistance during deposition is of primary relevance in the context of the morphology control of the nanocomposite films. This contribution will summarize our recent activities in the field of ionassisted physical vapor deposition (PVD) of carbon-transition metal films with the focus on the growth-structure relationship. This class of materials is relevant in the context of tribology, sensing, fusion, electrochemistry, information storage, spintronics or solar-thermal energy conversion. We have employed ionized physical vapor deposition in the form of a pulsed filtered cathodic vacuum arc (PFCVA) and ion beam assisted deposition (IBAD). The two methods differ in the way the ion energy is transferred into the near surface layers: for IBAD the bombarding Ar + ions transfer the energy via collisions to the near-surface layers of nanocomposite films while for PFCVA the energetic species are themselves the film forming material. The dependences of the film structure on the metal type, metal-tocarbon ratio, ion energy and ion incidence angle will be reported. The results show that ions have a dramatic effect on the film morphology resulting in a large variety of morphologies such as encapsulated nanoparticles, high aspect ratio nanocolumns or self-organized layered 3D nanoparticle arrays. The latter occurs only due to the presence of energetic ions, and the periodicity is determined by the ion energy. In addition, the ion induced atomic mobility is not isotropic, as it would be in the case of thermally excited migration, but conserves to a large extent the initial direction of the incoming ions. Independently of the growth regime, it results in the morphology tilt: metal nanopatterns no longer align with the advancing surface but with the incoming ions. Such effects allow 3D sculpting of nanocomposites which is due to ion irradiation effects and does not require any glancing incidence conditions. As the observed effects are of physical origin (ion-solid interactions), we believe that the presented results are applicable to other immiscible or partially miscible systems as well. This presents a possible path towards a material design approach based on material system independent tools to sculpt the morphology at the nanoscale in order to match the requirements of a wide range of applications. 5:10pm B1-2-12 The effect of hydrogen addition on the residual stress of cubic boron nitride film prepared by R.F. magnetron sputtering of B4C target, J.K. Park (jokepark@kist.re.kr), J.-S. Ko, W.-S. Lee, Y.J. Baik, Korea Institute of Science and Technology, Republic of Korea cBN (cubic boron nitride) shows outstanding mechanical properties such as hardness and wear resistance. In contrast to diamond, cBN is compatible with ferrous materials, which makes it possible to be used as coating materials for machining of ferrous materials at high temperatures. However, amorphous BN and hBN layers inevitably formed before nucleation of cBN weaken the interface stability between cBN film and substrate. Furthermore high stress developed during deposition of cBN film deteriorates adhesive strength of cBN film. Recently, the adoption of compositionally gradient B- C-N buffer layer [1] and the addition of oxygen [2] or hydrogen [3] have been suggested as useful technique to improve interface (hBN) stability and reduce residual stress of cBN film, respectively. By further reduction of residual stress of cBN film with stable interface of hBN layer, the application of cBN as protective coating material is believed to be realized. In this study, therefore, we have investigated the effect of hydrogen addition on the residual stress of cBN film prepared with compositionally gradient B-C-N layer deposited by magnetron sputtering of B4C target. The deposition was performed on Si (100) substrate under the chamber pressure of 0.27 Pa with substrate bias of -250V. After the deposition of B4C layer, up to 5 sccm hydrogen was added to a gas mixture of argon and nitrogen flowing 25 sccm and 5 sccm, respectively during sample preparation. The compressive stress of cBN film was observed to be decreased from 9.2 GPa to 4.3 GPa, with increasing hydrogen flow up to 5 sccm. The cBN fraction in these films, however, remained to be about 65%, irrespective of the amount of hydrogen added. The stress reduction observed in cBN film deposited with the addition of hydrogen was discussed in terms of the relation between the penetration probabilities of hydrogen and argon ions into the film, which was main origin of compressive residual stress of the compositionally gradient B-C-N layer with hBN structure.

Cremona, Pontificia Universidade Católica do Rio de Janeiro, Brazil 1:30pm C2-2/F4-2-1 Reactive Deposition of Aluminum-doped Zinc Oxide films using Asymmetric Linked Dual Rotatable Magnetron, M. Audronis (martynas.audronis@gencoa.com), V. Bellido-Gonzalez, Gencoa Ltd, UK Transparent conductive oxide (TCO) films are a widely used group of functional materials that can be found in a large variety of applications such as consumer electronics (e.g. flat panel displays and touch-screens), solar cells and smart glass/windows. Indium Tin Oxide (ITO) – the most widely applied TCO, exhibits excellent electrical and optical properties and good corrosion resistance. The drawback of ITO is that it is too expensive for the majority of low cost applications and, due to the rarity of In, has a potential to become even more expensive in the near future. Aluminum-doped Zinc Oxide (AZO) is considered to be one of the most viable alternatives to ITO in many application areas. Deposition of AZO by sputtering can be done non-reactively from ceramic targets or reactively from metal Al doped Zn targets. Reactive deposition mode, as compared to sputtering ceramic targets, offers significant cost savings on the target material and an increase in production rates. Operation in reactive mode however requires a stable and well controlled process. This concerns both, the reactive gas delivery (i.e. partial pressure) and plasma substrate interaction. In this paper we describe a reactive AZO deposition process using the recently developed asymmetric linked dual rotatable magnetron (ALDRM) sputtering technology. ALDRM lowers the impedance of plasma (hence increases the deposition rate at the same target voltage) and allows control of the plasma-substrate interaction degree. A fast feedback process control system is used in conjunction providing accurate reactive deposition process control and ensuring the required stability. The combination of the above mentioned methods yield AZO films of good electrical and optical properties at high deposition rates. 1:50pm C2-2/F4-2-2 Influence of the Kind and Content of Doped Impurities on Impurity-Doped ZnO Transparent Electrode Applications in Thin-Film Solar Cells, J. Nomoto, T. Hirano, T. Miyata (tmiyata@neptune.kanazawa-it.ac.jp), T. Minami, Kanazawa Institute of Technology, Japan Impurity-doped ZnO thin films that would be suitable for transparent electrode applications in Si-based thin-film solar cells must necessarily attain not only a decrease of plasma resonance frequency by lowering the carrier concentration while retaining a low resistivity, but also a significant scattering of the incident visible and near-infrared light by surface texturing the film. This paper describes the influence of the kind and content of dopant on the electrical properties and their stability as well as on the light management obtainable by surface texturing in impurity-doped ZnO thin films. Al-, Ga- and B-doped ZnO (AZO, GZO and BZO) thin films were prepared on OA-10 glass substrates at a temperature of room temperature (RT) or 200 o C using a pulsed laser deposition (PLD) and magnetron sputtering deposition (MSD). AZO, GZO and BZO thin films were prepared by PLD using an ArF excimer laser. AZO and GZO thin films were also prepared by direct current MSD with superimposed radio frequency power. The electrical properties were evaluated for impuritydoped ZnO thin films prepared with a thickness in the range from 0.5 to 2 μm, because the obtainable electrical properties were considerably dependent on the film thickness. In addition, for impurity-doped ZnO thin films prepared on substrates at 200 o C, the following characteristics were found to be considerably dependent on the content of impurity doped into the thin films, irrespective of the deposition methods used: the obtainable 11 Monday Afternoon, April 23, 2012
