Effect of abrasive particle size and the influence of microstructure on the wear mechanisms in wear-resistant materials

► Size effect of abrasive particles examined for WC-based coating and sintered WC. ► Influential parameters affecting the wear mechanisms have been examined and identified. ► Transition from plastic deformation to a more fracture related material removal observed. ► Parameters such as 'severity of contact' and 'brittleness factor' are defined to explain the behavior.
