Abstract. Effect of regular microrelief of friction surfaces with solid film coating on adhesion of the coating to the surface, friction coefficient, and endurance of friction couples at high temperature in vacuum is investigated. The coating on the base of molykote are analyzed. Vibratory burnishing of the surfaces to produce regular microrelief is shown to increase adhesion of the coating to the surface several times and allows for control over the coating quality.
Keywords: frequency couple, regular microrelief, friction coefficient, solid film coating, adhesion, vacuum, temperature.
