Aluminum Matrix Composites (AMCs) are well known for high strength to weight ratio, and high temperature applications. In the present study, wear behavior of alumina particles reinforced Aluminum Matrix Composites (AMCs) and brake disc material has been investigated. AMCs used in this study contain 30vol. alumina particles in Al alloys and was developed by squeeze casting. The wear rate was measured using a pin-on-disc type wear testing machine at room temperature under dry sliding condition. Wear rate was measured at 25, 50, 75 and 100N and sliding speed of 250, 500, 750 and 1000 rpm. The coefficient of friction of both AMCs and brake disc was also measured. The microstructures of both materials were also examined after each load. Results showed that wear rate increased with increase in load. The coefficient of friction was consistent up to 50 N load and then decreased at 75N and 100N. The microstructure showed that the AMCs experienced a combination of adhesive, abrasive and fatigue types of wear under various loading conditions. The coefficient of friction decreased as the surface of the AMCs become rougher at higher load. This was considered due to removal of alumina particles from the surface of AMCs during wear test and the remaining aluminum alloy without alumina particles made the material softer. © 2013 The Authors.
