Abstract
The article considers the issues associated with the resistance to vibrations and elevated temperatures of the antifriction high-temperature coating obtained by processing an aluminum alloy in selenium vapor. The statement about the low resistance of solid lubricant coatings to fretting wear is substantiated. The quality control of the antifriction coating is carried out using an electron microscope, and the mechanical properties of the surface layer of the samples are determined by the method of kinetic microindentation. The experiments were carried out on a testing bench with a cantilevered plate driven by an electromagnet, at the end of which a steel ball contacting with an aluminum alloy plate is installed. The fretting wear of a coating on a plate in contact with a steel ball is experimentally studied depending on the normal load. Particular attention is paid to the stability of maintaining a given temperature regime. Based on the study, it was found that the anti-friction coating has a low resistance to vibrations.
