In this study an attempt is made towards the formation of surface composite comprises of Silicon Carbide (SiC) on to the surface of AA 5086 aluminium alloy using Gas Tungsten Arc (GTA) as heat source. The effect on the hardness, wear and corrosion properties were evaluated. Except heat source current and torch speed the remaining parameters are kept constant. The variable process parameters are optimized according to the quality of fusion. The hardness of the SiC reinforced AA 5086 is 121 HV which is greater than the base metal hardness 101 HV by 20%. The wear rate of the surface modified AA 5086 was evaluated and found that it is reduced by 48%. The susceptibility of intergranular corrosion is determined by the mass losses of reinforced AA5086 and is less than that of the base metal. Characterization techniques like SEM, EDX and XRD is used. © 2017 Elsevier Ltd.
