Abstract

Wear resistance of the RS/PM Al-Si alloys in the two states was studied and compared with conventional casting wear resistant alloys ZL109. The results show that the wear resistance of the RS/PM Al-Si alloys is improved and wear resistance of the as-T6 alloy is superior to the as-extruded alloy. Wear mechanisms of RS/PM Al-Si and ZL109 alloys were studied. It is shown that the oxidation is dominant in wear of the RS/PM Al-Si alloys, but in wear of the Zl109 alloy,adhesion and plastic stripping is major.
