A mechanism for blocking and subsequent annihilation of endogenous microcracks due to their intrastructural self-correction has been proposed. It has been established that during tribomechanical processes of friction interaction under conditions of additive influence of temperature fluctuations and specific loads in the contact zone, all possible factors take place simultaneously, from the point of view of physicochemical anomalous transformations in the solid phase, as a result of which

The test results prove that the anti-friction surface layer, which contains graphite, is formed in the run-in regime. The composition and the equilibrium roughness of the surface layer are reproduced and maintained throughout the normal range of wear, and also form an integral system of dynamically stable wear-resistant structures.
