OPTIMIZATION OF PARAMETERS OF THE PLASMA SURFACE HARDENING PROCESS

Abstract

The purpose of this work is to improve the technology of production of mining machines, namely – the development and optimization of the parameters of the process of surface hardening of large-modulus gear wheels to increase the durability, longevity of gear drives of ore mills. The stated purpose of the work necessitated the solution of such problem as optimization of technological parameters of the regime of surface plasma-arc hardening by mathematical modeling in order to identify their influence on the relative lifetime of large-modulus gears.
