Study of Antifriction and Fatigue Properties of Molybdenum Disulfide–Based Suspension Coatings

This article presents the results of the ball-on-disk wear test (ASTM G99) and linearly reciprocating ball-on-flat sliding wear test (ASTM G133) for molybdenum disulfide–based coatings in a wide range of operating conditions. Monocomponent suspension coatings based on molybdenum disulfide and doped with graphite, ceramics, and polytetrafluoroethylene are studied in a vacuum, at elevated temperatures, and under normal atmospheric conditions. The friction coefficient and service life of the coatings are determined depending on the application technology and operating conditions. The structure and chemical composition of the coatings and the mechanisms of coating wear and destruction are studied.
