Investigate the Mechanical and Tribological Characteristics of Cu- Al2O3- Gr Composite via Stir Route

The present work examined Cu-Al2O3-Gr composites produced using stir casting and analyzed their mechanical properties. Additionally, the wear performance of these composites was evaluated concerning different reinforcement ratios. Three samples were analysed Pure Copper, 96% Cu, 2% Al2O3, 2% Gr, 95%...

description The present work examined Cu-Al2O3-Gr composites produced using stir casting and analyzed their mechanical properties. Additionally, the wear performance of these composites was evaluated concerning different reinforcement ratios. Three samples were analysed Pure Copper, 96% Cu, 2% Al2O3, 2% Gr, 95% Cu, 3% Al2O3, 2% Gr and 92% Cu, 3% Al2O3, 5% Gr. The incorporation of Al2O3 and Gr reinforcements significantly enhanced the hardness and tribological properties of these metal composites in comparison to pure copper. The potential enhancements in the lubricating and load-bearing characteristics of graphene in Sample 4, comprising 5% graphene, led to improved performance. An analysis of the microstructure of a worn surface from the study examining the distribution of reinforcement and its correlation with mechanical parameters. Wear studies were conducted under various situations to evaluate tribological performance. The results suggest potential uses of Cu-Al2O3-Gr composites in domains requiring strong abrasive wear resistance and enhanced mechanical properties, aiding in the determination of optimal reinforcing quantities for material development in demanding industrial settings.
