Implication

Comparative evaluation shows improved wear resistance in Cu matrix composites reinforced with various materials, suggesting optimal combinations for durability.

Key Points

This study aims to evaluate the microstructural, mechanical, and tribological properties of copper matrix composites reinforced with various materials.
Fabrication of Cu matrix composites using powder metallurgy
Analysis of phase constitution and microstructure via XRD, SEM, and EDS
Assessment of mechanical and tribological behavior through Vickers hardness and dry sliding wear tests.
Cu–B4C demonstrated 154.8% improvement in wear resistance compared to pure Cu.
All reinforced composites exhibited lower mass loss and more stable sliding behavior than unreinforced Cu.
Hardness increased across all composite materials, with Cu–B4C showing the highest increase at 68.91%.
