Influences of Solution Treatment, Deformation Strain, and Nanometric Al₂O₃ Particulate on Dry Wear Properties for Nanometric Al₂O₃ Particulate Reinforced Al Alloy Matrix Composites Manufactured by Casting

Abstract:

The influences of solution treatment, deformation strain, and nanometric Al₂O₃ particulate on dry wear properties for nanometric Al₂O₃ particulate reinforced Al alloy matrix Composites manufactured by casting were investigated. The result showed that both the wear resistance of AL matrix and the composites increased rapidly with increasing solution temperatures. The wear resistance increased slightly with increasing deformation strain for the composites. The wear resistance of the composites is higher than the AL matrix after the same deformation and heat treatment. Microstructure observation revealed that the grain sizes of the composites increased with increasing solution temperature and decreased with more severe deformation. Abrasive wear was the main wear mechanism both for the AL matrix and the composites.
