Mechanisms of structural thermal adaptability of silicate coatings

The present work describes the results of experimental research of surface layers of fine silicate coatings appearing due to the minerals, such as lubricating coatings as fillers. It is shown that the structure of protective films degrades primarily due to accumulation of impurities in the boundary layer and at the inter-phase boundary with the metallic substrate, particularly carbon promoting the formation of a larger amount of crystalline structure defects. The effect of sliding velocity on the wear resistance of the silicate coating is weighed. The compatibility of friction materials and minerals is advised in order to achieve the maximum efficiency of protective coatings.
