Abstract

Aluminium alloy-based metal matrix composites (AMMCs) have been considered as a potential material in various engineering and industrial applications due to their excellent combination of physical, mechanical and tribological properties. Reinforcing with different filler materials into the metallic matrix improves the hardness, stiffness, specific strength, wear resistance and fatigue properties of the materials in contrast with the conventional materials. The characteristics of aluminium alloy-based composite solely depend upon the type of fillers, interfacial bonding and different processing parameters. In this work, metal matrix composites have been fabricated by reinforcing Al2O3 in AA5754 matrix employing stir casting method. Mechanical characterisation, as well as the sliding wear test were carried out. The effect of the varying process parameters on the sliding wear properties has been investigated using Taguchi method and Grey Relational Analysis (GRA).
