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 ...

Broom-like and flower-like heterostructures of silver molybdate through pH controlled self assembly
Singh, D. P.; Sirota, B.; Talpatra, S.; Kohli, P.; Rebholz, Claus; Aouadi, S. M. (2012)Silver molybdate microrods are selfassembled into micron sized, broom-like and flowerlike structures. Our investigations indicate that through a simple hydrothermal process, large scale production of such structure is ...

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 ...

Room temperature synthesis and high temperature frictional study of silver vanadate nanorods
Singh, D. P.; Polychronopoulou, K.; Rebholz, Claus; Aouadi, S. M. (2010)We report the room temperature (RT) synthesis of silver vanadate nanorods (consisting of mainly β-AgVO3) by a simple wet chemical route and their frictional study at high temperatures (HT). The sudden mixing of ammonium ...

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 ...
