Abstract : There is a continuing requirement for improved bearing performance for both commercial and military applications. Service temperatures are increasing steadily due to increased power requirements and corrosion of components remains a major concern as well, particularly for bearings in military systems. In our ongoing study, a number of different coatings were applied to VIM-VAR M50 bearing steel to improve both corrosion resist ance and rolling contact fatigue behavior. This report deals specifically with coatings produced by the ion beam assisted deposition IBAD of TiN, details of the coating process, and test results obtained. The rolling for a 1 micrometer thick coating. Preliminary data on corrosion properties is also presented....
