Studies on wear characteristics of Al-Fe-V-Si alloys

This paper deals with the wear behaviour of modified and unmodified cast Al -Fe-V-Si alloys studied through pin-on-disc wear test under three loads, na mely 29.4, 49.0 and 68.6 N. Whilst all the alloys showed excellent wear res istance compared to the conventional eutectic Al-Si alloy, modification wit h Mg imparts further enhanced resistance to wear and reduced coefficient of friction. It was observed that during dry sliding wear extensive plastic d eformation, work hardening and oxidation of alpha-Al matrix occurred. It ha s been shown that the primary mode of wear is delamination. (C) 2000 Elsevi er Science S.A. All rights reserved.
