On the basis of thermodynamics of nonequilibrium processes the model is developed, allowing to predict wear resistance and others tribotechnical parametres hardloaded high-temperature interfaces. For the predicted adaptation of friction surfaces and a decrease in the wear rate, it is necessary to use tool materials and wear-resistant coatings containing chemical elements and compounds capable, under certain conditions, of chemically interacting with the material being processed and with the environment, creating non-equilibrium secondary structures with negative entropy production. Contributions of additional impacts on the cutting zone due to the use of coolant, unsteadiness of the cutting mode elements, and other relevant factors should also be considered.
