Abstract: Aluminum Metal Matrix Composites have been in extensive demand due to their promising properties with respect to space, aerospace and automobile applications. In the present research work aluminum-red mud particulates (Al-RMp) &aluminum-graphite particulates (Al-Grp) reinforced composites were synthesized by traditional stir casting route. The reinforcement was varied from 4wt% to 20wt% in steps of 4wt%. The composites thus prepared were subjected to 3-body abrasive wear test as per the ASTM-G65 standard with three different loads of 10kg, 20kg and 30kg. The test was conducted for three different time periods of 10min, 20min, and 30min. The rotational speed of rubber wheel was set to 200rpm.The feed rate of the silica particles of 400 microns size were 280Â±10 g/min. The specimens were also tested for hardness. The experimental results indicate that the hardness and the wear resistance of the composite increases with the increase in the addition of reinforcement particulate. Al-RMp composites exhibit higher hardness and better wear resistance compare to Al-Grp composites. Hardness and wear loss is quantified for all the test samples and reported.
