Wear Characterization of Aluminium Metal Matrix Composites

Abstract

Aluminium metal matrix composites wear characterization is presented in the paper. The LM25 grade aluminium alloy is chosen as matrix material and reinforcements are silicon carbide, zircon and garnet particles. AlMMCs are produced by conventional stir casting method and heat treated before making wear test specimens according to the ASTM G99 standards. The wear behaviour of these composites is studied under laboratory conditions using a pin-on-disc wear test rig. The wear behaviour of these composites is studied under sliding on EN32 steel disc. The influence of reinforcement type, volume fraction, particle size, sliding speed, applied load and sliding distance is analyzed.
