Active process control of reactive sputter deposition
Voevodin, A. A.; Stevenson, P.; Rebholz, Claus; Schneider, J. M.; Matthews, A. (1995)Control of the density, composition, ionisation rate and arrival energy of species is one of the main objectives of research in the development of reactive magnetron sputtering. The deposition of the latest generation of ...

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 ...
