In this study, the surface of an AA-2024 alloy was covered with reinforced composite coating using hotpress sintering method. Al and B 4 C powders were synthesized through mechanical alloying technique and coated on the AA-2024 substrate at different rates. The microstructure of the intermediate transition region formed between the substrate (AA-2024 Al alloy) and the coating layer (Al/B 4 C MMCs), the microstructure of the Al/B 4 C metal matrix composites (MMCs) coating, the microhardness, and the adhesive wear resistance of the Al/B 4 C MMCs coating layer were investigated. It was observed that B 4 C powders homogeneously dispersed in the microstructure of the Al/B 4 C MMCs coating layer, moreover, the Al matrix and B 4 C reinforcement particles were bonded without a gap. It was also determined that an interface bonding occurred between Al/B 4 C MMCs coating layer and the AA-2024 substrate. Accordingly, it was determined that with the increase of B 4 C reinforcement particle ratio, the hardness of the coating layer, and the wear resistance increased.
