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