Coating on Surface By Different Methods - a Review

Abstract

The material has different properties, because of this properties material have different application. Sometime due to chemical reaction corrosion is done on material surface, due to oxide material degradation is occur and impact of solid particles on surface erosion is occur. So to increase the corrosion resistance different kind of coatings can be done on surface like steel, aluminums, alloys. This corrosion decreases the life of the material and decrease the properties. For coating deposition laser cladding, magnetron-sputtering, thermal spray (HVOF) methods are use. This coating is requiring in aerospace application, oil and gas industries, high temperature application and turbine industry.
