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, namely 29.4, 49.0 and 68.6 N. Whilst all the alloys showed excellent wear resistance compared to the conventional eutectic Al–Si alloy, modification with Mg imparts further enhanced resistance to wear and reduced coefficient of friction. It was observed that during dry sliding wear extensive plastic deformation, work hardening and oxidation of α-Al matrix occurred. It has been shown that the primary mode of wear is delamination
