Controlling the Properties of the Surface Layers of Parts by Forming Regular Micro-Reliefs

Abstract

The paper focuses on a combined processing method developed to control the properties of the surface layer of parts. A regular micro-relief was obtained on the surface, with oil pockets to hold the lubricant during the friction process. Profilograms of samples processed by different modes and a model of the process of obtaining regular micro-relief are presented. We carried out comparative endurance tests of the samples processed by various methods. For the study the samples of steel 5140 (41Cr4) were selected. The results obtained allow us to recommend combined processing for the parts operating under conditions of intense friction with lubrication.
