In special machine elements, architectural sections, automobiles and frame systems, aluminium alloy 6063 has a wide application. AA6063 has a high strength to weight ratio, but poor wear resistance and hardness characteristics. Friction Stir Processing (FSP) is a method of surface modification in which the surface's mechanical properties can be enhanced by strengthening ceramic particles. The surface property of Aluminium Alloy 6063 is modified in this present investigation by strengthening the powder particles of Boron Carbide (B4C) through FSP. The distribution of B4C particles was investigated by keeping the volume fraction (22.38 percent) constant for various reinforcement techniques, based on hardness and impact power. The tool pin profiles such as the threaded cylindrical and square pin were also compared via various reinforcement techniques for the best distribution of B4C in the base metal surface. The tool has a rotational speed of 1200 rpm, a travel speed of 40 mm / min and an axial force of 10 kN. By strengthening Boron carbide particles into the base metal surface, friction stir processing is an efficient way to increase hardness. When the B4C particles are packed into the serial holes and friction stir is processed with the square pin profile tool, the optimum hardness and impact strength is achieved. The uniform distribution of B4C particles is demonstrated by increased hardness in the Stir field. For surface modification via FSP, the serial holes reinforcement method with a square pin instrument may therefore be used.
