Abstract
Surface coatings offer a wide range of purposes to get good properties of the components. There are more applications of surface coatings in different industries to improve the properties of substrate such as sports technology, automotive industries, chemical and petroleum, physical and electronic, decorative coating and thermal barrier coatings meter. Recently, surface coatings have been developed progressively in some specialized parts to enhance wear resistance and reduce diffusion and friction. In this study three samples were prepared by covering two welded pieces of low carbon steel with the ceramic material (mullite powder (3Al2O3.2SiO2) for the ratio of (0% as a control, 5%, 10%) and by adding varnish and thinner that were used as a binder material for reinforcement low carbon steel in welding region. Then study different properties of coating layer such as the thickness of the coating layer, contact angle, and roughness, finally examine the hardness test, wear test and Atomic Force Microscopy.
