Abstract The wear behaviour of varying size and weight fraction of particles up to 30 wt% Al 2O 3 particles reinforced 2024 Aluminium alloy Metal Matrix Composites (MMCs) fabricated by a vortex method was investigated in a pin on disc abrasion test apparatus against different SiC abrasives at room conditions. Wear tests performed under the load of 2 N against SiC abrasive papers of 20 (600 grit), 46 (320 grit) and 60 μm (240 grit). The effects of sliding distance, Al 2O 3 particle content and size, and abrasive grit sizes on the abrasive wear properties of the composites have been evaluated. The main wear mechanisms were identified using a scanning electron microscope. The results showed that Al 2O 3 particles reinforcement improved the abrasion resistance against all the abrasives used, and the abrasive wear resistance decreased with an increase in the sliding distance and the abrasive grit size. The wear resistance of the composites was considerably bigger than that of the aluminium alloy and increased with increasing Al 2O 3 particles content and size.
