Copper alloy Bronze-RG10 is a high-density hard material with good resistance to traction, wear and tear used in gear applications. The wear and hardness of the alloy can be further improved by reinforcing with hard particles. Hence, this study fabricated the behaviour of copper alloy B-RG10 composites reinforced with titanium carbide (TiC) and graphite particles using the powder metallurgy process. The effect of TiC and graphite reinforcement in copper B-RG10 alloy metal matrix was studied at the different weighted compositions of reinforcement (3%, 6%, 9%, and 12%). The fabricated composites were tested for Rockwell hardness, wear, and microstructures. With the increase in reinforcement, the hardness of composites increased due to the addition of TiC particles to the B-RG10 matrix. The density decreased due to increased porosity and work hardening effect. The optical microscopy and SEM micrograph showed that TiC and graphite particulates were uniformly distributed into copper metal matrix leading to better mechanical properties. With the increase in TiC and graphite wt.%, a significant reduction in wear rate was observed. The composite with 6 wt% TiC and 6 wt% graphite showed the lowest wear rate. Based on the results obtained in this study, it was concluded that the addition of TiC and graphite in copper alloy B-RG10 alloy enhanced their hardness and wear behaviours and made the composites suitable for applications in sliding wear and coupling parts in the aerospace and automobile sectors.
