Al alloys because of their desirable characteristic properties have made them predominant materials in lightweight design structures such as the aviation, automotive, and shipbuilding industry. However, their applications are limited due to their lower strength at higher operating temperature and difficulty in their welding. One of the alternatives to enhance the surface properties of aluminium alloys is coating metallic substrates. In the present experimental study, the effect on surface properties by introducing titanium and silicon carbide reinforcement into AA5083 alloy using friction stir processing (FSP) was investigated. Additionally, bead geometry such as the width of SZ, depth of SZ, and area of SZ in all the specimens were also analyzed. FSP was performed at different combinations of rotational speeds, traverse speeds, and shoulder diameter sizes using Taguchi L4 orthogonal array. Experimental results indicated that the highest value of hardness was observed at tool rotational speed of 355 rpm, traverse speed of 63 mm/min, and shoulder diameter size of 17 mm. Moreover, at such combination of process parameters, the lowest value of width to depth ratio was observed.
