We propose a mechanism for increasing the durability of friction surfaces in the presence of in-service defects caused by the intrastructural regeneration. It is shown that, in the case of frictional interaction under the conditions of additive influence of temperature fluctuations and specific loads, all possible abnormal physicochemical transformations in the solid phase simultaneously run in the contact zone. This results in the thermal decomposition of carbides and in the formation of structurally free α -graphite. On the basis of the experimental data, it is assumed that the antifriction graphite-containing surface layer formed in the running-in mode is reproduced with the formation of an integral system of dynamically stable wear-resistant structures in the entire region of normal wear.
