ANALYSIS OF THE WEAR PROCESS OF SURFACE LAYERS AFTER BURNISHING

Abstract

The paper presents the results of an analysis of the wear process under conditions of dry technical friction of surface layers after selecting external surface pressure burnishing methods. The possibility of making changes in the burnishing process leading to an increase in resistance to wear under conditions of a simulated exploitation process is described. The possibility of conscious control of the process of material deformation in the zone of contact between the tool and the workpiece in the course of the surface layer formation process by changing the method and technological parameters of the pressure burnishing process is used. The course and results of the wear process of surfaces pressure burnished with a rolling ball, disc, and sliding ball are analysed. A description of the wear mechanism and comparative results of the wear of the surfaces tested are presented.
