Tribological Investigations of Composites and Other Selected Materials Sliding Against Vacuum-Deposited NoS2 Coatings

摘要

A new materials approach for rolling element bearings in space satellite systems involves the use of rolled lubricating retainers and pre-MoS, vacuum coated bearing elements. Improved vacuum deposition methods are now available to produce dense, suitably oriented, durable films of molybdenum disulfide. It is of interest to examine materials in sliding contact with such films in order to identify suitable combinations, and to further improve tribological performance of the smitten. Results of wear and friction measurements are presented on a number of materials including self-lubricating composites sliding against four different types of vacuum-deposited MoS2 films.
