Wear Behavior of Al-Al₂O₃ Reinforced Composites

Abstract:

Aluminum composites containing 10wt. % of Al₂O₃ with 3 µm size of particles have been produced using powder metallurgy (PM) method and wear behavior of the composites were tested under dry condition. A comparison is also made with SiCp reinforced Al composite produced at the same conditions. The wear rate of both types’ composites increased with all applied loads, but wear rate of the composites was a strong function of normal load rather than that of type of particles used for the manufacturing MMCs. Furthermore, the wear rate of Al-Al₂O₃ composite was smaller than that of Al-SiCp reinforced composite, but not indicating significant differences on it. Moreover, SEM examination showed that plastic deformation was the dominant type of wear for the Al₂O₃ particle reinforced MMCs, but the fragmented-deformed layer of particles was more effective for the SiCp reinforced MMCs due to more fracturing of particles.
