Abstract: In this work, a systematic study has been done on mechanical and abrasive wear behaviour of friction stir processed (FSP) Al7075 alloy marble dust reinforced surface composites. Selected friction stir parameters are varying tool feed rate (10 mm/min, 20 mm/min, 30 mm/min and 40 mm/min) fixed tool rotation speed (1,000 rpm), and zero-degree tilt angle using the conical shape tool. Mechanical properties, i.e., hardness, tensile, and impact strength of the fabricated surface composites are evaluated experimentally. Four control parameters with four levels of each, i.e., FSP tool feed rate (10 mm/min, 20 mm/min, 30 mm/min and 40 mm/min), counter (1,000, 1,500, 2,000 and 2,500), abrasive wheel speed (100 rpm, 150 rpm, 200 rpm and 250 rpm), and load (10 N, 20 N, 30 N and 40 N) are selected for dry sand abrasive wear tests. Results show the improvement in hardness, tensile strength, impact strength and wear resistance with the increase of FSP tool feed rate up to 30 mm/min.
