      Effect of Cu content on the tribological performance of Cr-N coatings at high temperatures (840°C) 

      Polychronopoulou, K.; Rebholz, Claus; Demas, N. G.; Polycarpou, A. A.; Gibson, P. N. (Affiliation: Department of Mechanical and Manufacturing Eng., University of Cyprus, Nicosia, CyprusAffiliation: Department of Mechanical Science and Eng., University of Illinois at Urbana-Champaign, Urbana, IL, United StatesAffiliation: Institute for Health and Consumer Protection, Joint Res. Centre of the European Commission, Ispra (VA), ItalyCorrespondence Address: Polychronopoulou, K.Department of Mechanical and Manufacturing Eng., University of Cyprus, Nicosia, Cyprus, 2010)
      Cr-N and Cu-Cr-N coatings with Cu content between 3-65 at.%, Cu/Cr ratios in the 0.04-4.5 range and 21-27 at.% N, synthesized by twin e-beam Physical Vapor Deposition (EBPVD) at 450°C, were investigated. Using X-ray ...

      Evaluating the microstructure and performance of nanocomposite PVD TiAlBN coatings 

      Baker, M. A.; Klose, S.; Rebholz, Claus; Leyland, A.; Matthews, A. (2002)
      Physical vapour deposition (PVD) TiAlBN coatings can exhibit excellent wear resistance, with optimised coating compositions demonstrating a 150% increase in lifetime compared to standard TiAlN coatings in wet-cutting drill ...

      Multilayer composite ceramic-metal-DLC coatings for sliding wear applications 

      Voevodin, A. A.; Schneider, J. M.; Rebholz, Claus; Matthews, A. (1996)
      The design of anti-friction coatings able to perform well in different wear conditions without lubricants requires a combination of adequate hardness and toughness, good adhesion, a low friction coefficient and a low wear ...

      Structure, mechanical and tribological properties of nitrogen-containing chromium coatings prepared by reactive magnetron sputtering 

      Rebholz, Claus; Ziegele, H.; Leyland, A.; Matthews, A. (1999)
      Cr(1-x)N(x) coatings were deposited by magnetron sputtering at a substrate temperature of 200°C onto AISI 316 stainless-steel substrates immersed in an Ar/N2 plasma. The goal of this investigation was to study the influence ...

      Structure, mechanical and tribological properties of sputtered TiAlBN thin films 

      Rebholz, Claus; Schneider, J. M.; Voevodin, A. A.; Steinebrunner, J.; Charitidis, C.; Logothetidis, S.; Leyland, A.; Matthews, A. (1999)
      TiAlBN films were produced by simultaneously sputtering from TiAl and TiB2 targets in Ar/N2 mixtures at a substrate temperature of 150 °C. The goal of this investigation was to study the influence of the nitrogen content ...

      Wear behaviour of carbon-containing tungsten coatings prepared by reactive magnetron sputtering 

      Rebholz, Claus; Schneider, J. M.; Leyland, A.; Matthews, A. (1999)
      W(1-x)C(x) coatings (with x being in the range of 0.05-0.19) were deposited by reactive magnetron sputtering on to AISI 316 stainless-steel substrates in order to study the influence of the carbon content on the tribological ...

      Wear resistant composite coatings deposited by electron enhanced closed field unbalanced magnetron sputtering 

      Voevodin, A. A.; Rebholz, Claus; Schneider, J. M.; Stevenson, P.; Matthews, A. (1995)
      There is presently considerable interest in wear resistant coatings produced using closed field unbalanced magnetron sputtering technology. For example, layered films of diamond-like carbon (DLC) with tungsten or titanium ...
