Influence of different reinforcing particles on the scratch resistance and microstructure of different WC-Ni composites

WC composites are largely used in many engineering and industrial fields such as mining, cutting tools, and underground works. This interest in WC materials is related to their high wear resistance due to their convenient mechanical properties and controllable microstructures. However, the abrasive behavior of WC materials is very complicated because they are formed from several phases and their damage mechanism involves numerous parameters and factors that may be related to the composites themselves and the external environment. Reinforcing particles play a critical role in the achievement of wear-resistant materials. In this study, the impact of the presence of different types of reinforcing particles in the chemical makeup of WC-Ni composites on their resistance to scratch formation is highlighted through experimental abrasion tests by a single diamond tip.
