Wear assessment of Al/Al2O3 nano-composite surface layer produced using friction stir processing

▶ Using the innovative technique of friction stir processing (FSP). ▶ Fabricating a nano-composite surface layer. ▶ Using FSP process parameters to achieve sound surface layer. ▶ Using various FSP passes to achieve uniform dispersion of nano-sized particulate in the fabricated surface nano-composite layer. ▶ Assessment of dry sliding wear properties of the fabricated nano-composite surface layer and the as-received Al substrate. ▶ Assessment of wear under various applied loads.
