Friction stir processing Technique is used to modify the surface layer and improves the micro-structural modification and enhances the mechanical & wear properties of the material. In this study the effect of number of FSP passes on the Aluminum 1050 alloy was studied. The grain refinement of the matrix was obtained after each FSP pass. With increase in FSP passes decreases the grain size of the matrix alloy and more homogeneous grain refinement occurs on the stir zone. The hardness, tensile strength and wear rate of the processed region was evaluated and found that enhancement of hardness, tensile strength and wear resistance of the samples with increase in passes due to finer refinement of the grain size in the stir zone.
