Surface Layer Modelling for Materials under Thermal Hardening Process

Abstract

classification of the work tool’s heat removal system was made via the analytical researches of the thermal physics of the thermal hardening processing of the machine parts' surfaces and on the basis of numerical and physical simulation of processes that take place in the contact area, with the aid of mathematical models for the effective relevant parameters. These parameters made it possible to implement the material nano-structuring of the surface coating. It was determined that the material nano-structuring of the parts of surface coating during that process using the criteria of plastic structure formation and processing rate is generally effective when the work tool with the in-line cooling heat removal system of the hollow indenter is used by the lubricating/cooling  medium under pressure.

Keywords: heat removal, indenter, model, surface coating, thermal hardening.
