Aluminium based hybrid metal matrix composites (MMC's) are widely used in aerospace, automobile, transportation, marine, mineral processing and electrical packaging industries, because these composites exhibit low density, high specific strength and stiffness, high conductivity and corrosion resistance. In this work, an attempt has been made to reinforce the alumina(4, 8, 12 wt.%) and moybdenum disulphide(2, 4, 6 wt.%) with Al7075 alloy to improve mechanical and tribological behaviour of the hybridMMC's. Microstructural analysis of the hybrid composite specimens were carried under metallurgical microscope to decide uniform distribution and good bonding of Al2O3 and MoS2 reinforcement with aluminium matrix. Prepared hybrid composite specimens will undergo mechanical and wear testing to evaluate its hardness, tensile strength, percentage of elongation and wear rate.
