The major problem confronting aluminium alloy in various fields of engineering is based on the structural and continual failure of a component in service. The difficulties encountered are resolved through addition of RHA as strengthening agent to the aluminium metal matrix composite. The fabrication of MMC (AA6061/RHA) using metallurgical stir casting route in the array of 2, 4, 6 and 8 wt. % of RHA was done. Polarization test carried out in 0.75 M of H2SO4 on the composite shows enhanced corrosion susceptibility. Mechanical properties such as microhardness and tensile were performed on the developed composite. Corrosion analysis of RHA embedded in AA6061 revealed improved corrosion performance. Furthermore, the microstructural change through SEM shows that the incorporation of RHA in AA6061 aluminium alloy minimize corrosion effects. It also shows the homogenous dispersal of the fortification along the grain boundaries and reduced fracture propagation.
