In this study, a relation between reinforcement particles’ quantity variation and wear behaviour along with hardness properties of the aluminium-based functionally graded material (FGM) was established. Alumina particles were reinforced in aluminium-based functionally graded metal matrix composite, and the composites were manufactured by centrifugal casting at a constant speed. The matrix of the composite was a non commercial aluminium alloy, and Al2O3 particles, with an average grain size of 80 μm, were used as reinforcement. The reinforcement was varied in the range of 3.0–7.5 vol.%, and all the samples were prepared as per the ASTM standards. A pin-on-disc tribometer was used to study the sliding wear behaviour of composites. During the wear test, the speed of the disc was kept constant (0.5 m/s) and load was varied (20 and 25 N) at room temperature. The disc was made of AISI 52100 steel and acted as counter-body. In centrifugally cast metal matrix composite, the accumulation of alumina particles was found towards the outer region of the casting, which also showed an increase in the microhardness in that region. Wear testing indicated comparatively less wear towards the external zone of the castings.
