      Adaptive VN/Ag nanocomposite coatings with lubricious behavior from 25 to 1000 °c 

      Aouadi, S. M.; Singh, D. P.; Stone, D. S.; Polychronopoulou, K.; Nahif, F.; Rebholz, Claus; Muratore, C.; Voevodin, A. A. (2010)
      A two-phase nanocomposite coating that consists of inclusions of silver in a vanadium nitride matrix (VN/Ag) was investigated as a potential adaptive coating with a reduced friction coefficient from 25 to 1000 °C. This ...

      Composite DLC-metal/metal-carbide coatings produced by electron enhanced unbalanced magnetron sputtering 

      Rebholz, Claus; Ziegele, H.; Voevodin, A. A.; Schneider, J. M.; Matthews, A. (1997)
      Composite coatings consisting of metal containing diamond like carbons were produced by unbalanced magnetron sputtering in a closed field magnetic configuration. Targets of Pta and W were poisoned with acetylene during the ...

      Layered atomic structures of double oxides for low shear strength at high temperatures 

      Stone, D.; Liu, J.; Singh, D. P.; Muratore, C.; Voevodin, A. A.; Mishra, S.; Rebholz, Claus; Ge, Q.; Aouadi, S. M. (2010)
      Double oxide phases combining a transition metal and a noble metal have recently become a subject of investigation as solid lubricant materials for high-temperature tribological applications. Here, we study the changes in ...

      Local structure and influence of bonding on the phase-change behavior of the chalcogenide compounds K1-xRbxSb5S8 

      Wachter, J. B.; Chrissafis, K.; Petkov, V.; Malliakas, C. D.; Bilc, D. I.; Kyratsi, Theodora; Paraskevopoulos, K. M.; Mahanti, S. D.; Torbrügge, T.; Eckert, H.; Kanatzidis, M. G. (2007)
      KSb5S8 and its solid solution analogs with Rb and Tl were found to exhibit a reversible and tunable glass→crystal→glass phase transition. Selected members of this series were analyzed by differential scanning calorimetry ...

      The nanostructure, wear and corrosion performance of arc-evaporated CrBxNy nanocomposite coatings 

      Polychronopoulou, K.; Baker, M. A.; Rebholz, Claus; Neidhardt, J.; O'Sullivan, M.; Reiter, A. E.; Kanakis, K.; Leyland, A.; Matthews, A.; Mitterer, C. (2009)
      The composition, nanostructure, tribological and corrosion behaviour of reactive arc evaporated CrBxNy coatings have been studied and compared to CrN. The CrBxNy coatings were deposited on a commercial Oerlikon Balzers RCS ...

      Textured VN coatings with Ag3VO4 solid lubricant reservoirs 

      Luster, B.; Stone, D.; Singh, D. P.; Baben, M. to; Schneider, J. M.; Polychronopoulou, K.; Rebholz, Claus; Kohli, P.; Aouadi, S. M. (2011)
      Silver oxovanadate powders were produced using a low temperature hydrothermal synthesis method. X-ray diffraction (XRD) and Raman microscopy revealed the formation of the α-Ag3VO4 phase, and differential scanning calorimetry ...
