Friction Stir Processing (FSP) is generally used as a novel method for surface properties enhancement. The surface developed through FSP alters the tribological and mechanical properties of the material in a single step. This commendable enhancement in the properties by recrystallized equiaxed microstructure attained by dynamic recrystallization can be achieved in just one step there by increasing the performance. In this study, the effect of the FSP passes on the tribological & mechanical properties such as hardness, wear resistance and tensile strength for commercially available AA7075-T651 of 6mm thick sheet was studied. Properties in terms of hardness, wear rate and tensile strength were compared with the base alloy and Friction Stir Processed (FSPed) alloy. It was observed that the hardness, wear rate of the FSPed FSP3 was enhanced by 44% and 60% as compared to that of the unprocessed sample.
