Kinetic, thermofluctuation nature friction surfaces of solid friction during wear

The article describes the basics of the kinetic theory of strength and the thermofluctuation mechanism of destruction of the friction surfaces of solids during wear. The relationship of strength with the mechanical and physical constants of a solid is analyzed. The kinetics of the state of materials of the surfaces of friction pairs in the process of wear is studied. The temperature-time dependence of changes in the physical, mechanical parameters of materials and the destruction of surfaces and near-surface layers of friction pairs is confirmed. The basic principles of the physical model of damage to friction surfaces are formulated and the activation parameters of the thermofluctuation model of their destruction are estimated. A calculation model of friction wear based on the thermofluctuation fracture concept is proposed.
