Fabrication and wear performance of M7C3 carbide reinforced epoxy composites

The role of materials in industrial engineering has become even more important today. Various methods are used to develop materials with desired properties. Cr7C3 carbide and grease oil reinforced epoxy-based matrix composites were produced. Microscopic analysis of the composites was carried out by SEM. The differences in the wear properties of the composites were investigated in dry sliding wear test. Increasing sliding speed and load increased the wear of the composites. Combining Cr7C3 with epoxy resulted in improved wear performance. The higher the chromium carbide level increased the coefficient of friction. The best wear resistance result was obtained from 75 wt.% chromium carbide reinforced composite. The change in wear resistance varied significantly depending on the epoxy resin ratio and the amount of reinforcement.
