Assessment of cermets performance in erosive media

Ceramicmetal composites are a success story from the viewpoint of their many applications. However, the lack of design criteria and predictive models for durable applications of cermets poses a significant barrier to their wider application. The main objective of this paper is to review the cermets behaviour in tribological environment for better understanding material performance and durability in erosive media. For this reasons, microstructure of multiphase materials, features of structure development during sintering, fracture mechanisms, interface phenomenon, ability of energy dissipation and thermo-mechanical parameters were analysed with reference to WC-, TiC-, and Cr3C2-based cermets.
