Review on Thermal Spray Coating Methods and Property of Different Types of Metal-Based Coatings

To enhance performance of industrial tools and components, deposition of thin film or coating presents a good option. Coating is done on the surface of the objects such as machine parts, tools, and on other similar components. For protecting components from erosion, wear, and corrosion, this method presents a cost-effective method. Thermal spray is one of the coating methods. Thermal spraying is a well-known technique in industries for improving the surface properties of the components. Thermal spraying can be used to apply coating of different materials such as metals, ceramic blends, alloys, and carbides many more on variety of components. Thermal spray provides benefits like repairing engineering component, improves performance, and extended life of the components. Many materials can be deposited through thermal spray coating such as Zn, Al, Ni, WC, Fe, Cr, and even the combination of materials. These coatings have considerable effect on performance without affecting environment.
