| Abstract | ||
| Dry sliding wear test of the A1 matrix with 15% ceramic reinforcements of AI2O3 or Sic particles were performed using a pin-on-disc machine. The composites weqe prepared by powder metallurgy techniques followed by extrusion process. Some factors such as loads and sliding time on the degree of wear of particulate metal matrix composites (PMMC) were carried out. Tests were performed under different loads at room temperature and constant sliding speed of 1.67 mls. Results indicate that the addition of A1203 and Sic particles in the AI matrix improve the wear resistance and hardness. PMMC with A1203 showed better performance than Sic reinforcement. SEM tests were carried out to reveal complex combination of wear mechanisms on the surface of the worn test specime | ||
