Abstract:

 The application of coatings based on fluorocarbon polymer composition, frictionmechanical brass, fullerene C60 and surface treatment of vibrorolling with the regular roughness for the protection of heavily loaded mating parts of machines, working in conditions of frettingcorrosion. Studied the mechanisms of friction of coating, which will considerably reduce the fretting-wear mechanisms of friction in engineering products. It is established that in all studied for the protection of heavily loaded mating parts of machines is a single mechanism of increasing wear resistance when fretting in the area of the contact layer of the fine particles through the use of thin-layer coatings. Their presence may be due to either structural self-organization material, or forming of composite structures with small wear particles when using the polymeric composition. At that the protective coating virtually eliminates component corrosion mechanism of fretting – wear.
