In the work, analytical calculations are carried out and the nature of the distribution of heat fluxes in the cutting zone when using wear-resistant coatings is established. Thermophysical phenomena in the cutting zone are modeled when using composite wearresistant coatings on a cutting tool with the effect of self-organization under friction conditions. To confirm the phenomenon of self-organization and redistribution of heat fluxes in the contact zone, a series of adhesive, wear-resistant, temperature and force studies were Вестник Тверского государственного технического университета. Серия «Технические науки». № 3 (11), 2021 43 carried out when turning various grades of steels and alloys. An increase in the wear resistance of a cutting tool with a multilayer composite coating is established by redistributing the heat flux in the cutting zone due to the formation of protective shielding secondary structures.
