THE INFLUENCE OF EQUILIBRIUM QUALITY PARAMETERS OF A SURFACE LAYER ON THE WEAR RESISTANCE OF PARTS
Journal Title: Tribologia - Year 2014, Vol 257, Issue 5
Abstract
The article describes the processes of hardening and softening of the surface layer of parts in the process of wear during the formation of the equilibrium state of work surfaces of friction units. Based on the energy approach to the problem of the determination of the relationship of the wear rate of the contacting surfaces of machine parts with the quality parameters of the surface layer, the equation for the calculation of the linear wear rate in the equilibrium state is shown. The equation contains the following variables of basic surface quality parameters: the roughness parameter, the degree of hardening of the surface layer, operating stresses in the surface layer of machine parts, and the depth of hardening. The possibility of determining the relationship of the wear rate with the technological conditions of machining is shown.
