Abstract

The aim of the study was to investigate the effect of oxidation on the behaviour of TiC-based cermets with Ni-Mo binder under low intensity wear conditions in silica sand medium. Three types of material performance maps were constructed: oxidation rate map, wear rate map and map showing the effect of oxidation on wear. Discussion on the performance of cermets is based on oxidation, wear, SEM, EDS and XRD results. It is shown that cermets behaviour is highly influenced by microstructure (Ni, Mo content and Ni:Mo ratio) and oxidation kinetic. The paper should facilitate the optimization of TiC-Mo2C-Ni cermets selection for room and high temperature wear applications.

Keywords
