Metal Matrix Composite Coatings as wear resistant coatings and thermal barrier coatings play a crucial role in the life of current tribological and high temperature applications. Understanding the surface of these coatings in terms of its material structure, porosity, composition, mechanical strength, and bond strength is crucial. These properties essentially govern the final tribological and thermal properties and thereby dictate the life of the coatings. Various characterization techniques have been employed in studying the properties of the coatings. Proper choice of the characterization techniques; tools and method of evaluation are critical for distinguishing coating with very similar properties. This article presents the use of selected characterization techniques like Micro hardness, Scanning electron microscopy coupled with EDS, Image analysis, XRD and Surface Profilometry to analyze the mechanical, material and surface properties and understand the structure property correlation of coatings of varied microstructures with different volume fraction of ceramic particles embedded in metallic matrix.
