Selection of the optimal reparation technology for working parts subjected to abrasive wear

Abstract

The aim of this paper is to perceive possibilities for extension of the working life of parts exposed to abrasive wear. For this problem to be successfully solved it is necessary to understand the mechanism of abrasive wear which leads to damage of the working pairs. The optimal technology of hard-facing is determined based on voluminous model investigations, where the microhardness and wear resistance of the hard-faced layer were examined. The selected technology was then tested on the real hard-faced parts.
