People, materials, and engineering have developed over the passage of time and are enduring to do so [1]. Metal matrix composites are major innovation that results from a combination of two or more materials (one of which is a metal and the other a nonmetal) and most widely used in aerospace, defense, automobile and in general engineering purposes because of their high strength, stiffness, better wear resistance property and low density [2-3]. Various aspect of wear behavior and effects of reinforcement particles have been investigated. Madeva Nagarall et al. [4] reported Effect of Al_2O_3 Particles on Mechanical and Wear Properties of 6061Al Alloy Metal Matrix Composites. Md Al Mehedi et al. [5] reported the tribological characteristics of Al matrix composites reinforced with SiC & Al_2O_3.
