Thermal spraying is a new technology to stengthen surface of material and maintain size of works. It is widely used to maintain and repair parts in power plants. This paper simply introduces practice theory and application of thermal spraying, and then summarizes the application in power plant key components, such as boiler pipe, blades of fan and steam turbine, thermocouple sheath and so on. Thermal spraying should be promoted and developed powerfuly, because it has extensive market prospect. At the same time, it will bring more and more society and economic benefits.
