Dry Sliding Wear Behavior of Powder Metallurgy Aluminium Matrix Composite

This paper aims to study the effect of sintering temperature on physical, mechanical and wear properties of Al 2219 alloy matrix reinforced with SiC particulates of average particle size 23 mu m for different weight fractions 10%, 15% and 20% fabricated by powder metallurgy (PM) method. The influence of sintering temperature on mechanical behavior and dry sliding wear behavior were investigated. Wear tests were performed under the loads of 10 N, 20N and 30N and sliding distances of 1960 m, 2448 m and 2934 m at the room temperature. A detailed investigation was done to study the effect of sintering temperature on wear of the composite material during the wear test. It was found that the better wear performance for the composite material was obtained with finer size of the reinforcement, high weight fraction and high sintering temperature where the pooling of reinforcement can be avoided to an appreciable amount.
