The composites refer to the material consisting of two or more individual constituents, in that the reinforcing particulates are embedded to the base matrix to form composite materials by improving the mechanical and tribological properties. Different types of composite materials are available and these are increasing because of their good enhanced properties, among these Metal Matrix Composites (MMCs) finds its applications in various aspects like aerospace, automotive, defense, and marine etc. These improved properties are obtained from different form of particulates which are different in their aspect ratio are mixed with base material to provide good bonding and strength between them. To obtain these enhanced properties different manufacturing techniques are followed to prepare the composites. This paper presents an overview of types of composites, different fabrication techniques available to prepare the composites and also wear behavior of particulates reinforced MMC's by studying different types of wear mechanism.
