Investigations on the properties of industrial ceramic coatings and characterization

Abstract

Thermally sprayed ceramic coatings are more generally used on industrial components for meeting their functional requirements like high strength at elevated temperatures resistance to chemical degradation wear resistance and environmental corrosion protection in Engineering components The design of an engineering component which basically involves the design of enveloping surface of the components are achieved with some suitable modification techniques High Velocity Oxy Fuel and Plasma spraying are more precise to achieve thinner coatings without affecting substrate quality HVOF spraying process has been used for thermal spraying of bonding material and plasma spraying process is widely used for the deposition of films hard materials such as ceramics on relatively softer substrate Before deciding on a particular type of coating, it is necessary to look into essential characteristics related to mechanical and tribological properties in addition to their machinability characteristics for control of surface quality of end products
