Surface metal matrix composites are considered as new group of newer engineered materials in which the surface of the bulk materials is modified by reinforcing the hard ceramic fine particles. Because of the enhanced properties of the materials, these groups of materials found variety of applications in different fields like biomedical, aerospace, power sectors and automobile industries. Even though different processes are there to prepare these surface composites, Friction stir processing is gaining attractiveness in producing surface composites due to its processing in solid state. In the present experimental work, Silicon carbide particles are dispersed in the surface of the Al 6063 base materials and studied the microstructure of the processed specimens. Totally four experiments were conducted using two different pin profiles such as cylinder and square. Spindle speed and tool traverse speed is changed in two different levels and specimens were prepared using vertical milling machine. The processed specimens were examined for its microstructure and results revealed that square pin tool has performed better in terms of forming the better surface and stirring the reinforcement particles in matrix aluminum specimen.
