Features of high-speed wear of WC-steel 11G13 material in contact with cast tool steel

Abstract

The tribological behavior of WC-steel 11G13 composite material in contact with cast tool steel is considered over a sliding speed range of 10-40 m/s under a pressure of 2 MPa. The after-test surface structure is examined. Catastrophic wear of the material is proved to occur within a 23-30 m/s sliding speed range. It is shown that the sharp (fourfold) increase in the wear rate within the given speed range is related to a change in the wear mode. The subsurface region of the WC-steel 11G13 material is found to have a multilayer structure, the layers differing greatly in their properties and structure.
