Аннотация

A new process known as nanostructuring burnishing has been developed earlier for improving surface quality and physico-mechanical characteristics of a component by nanostructuring the subsurface layer microstructure. At that the surface modification is controlled by numerous parameters like loading force, friction coefficient, tool's tip radius, strain rate, and number of tool passes. Each of the above-mentioned process parameters has its own specific contribution to the severe plastic strain-induced structural evolution. In this paper we determine two basic integral parameters which would allow controlling the total process of strain accumulation as well as the surface quality obtained. These parameters are friction force and loading repetition. Results are verified by physical modeling by the example of HRC55 20Cr4 steel samples.
