Abstract

In the thermal power plants, the conventional steels used in boilers are unable to sustain the hot corrosion issues. To reduce the problem of hot corrosion in the boilers, many types of surface coatings have been used in the recent past. Thermal spray techniques have been used to develop these coatings on the components of boilers. Thermal spray coating techniques are important means to develop coatings to increase the corrosion resistance to enhance the performance and life of components. These coatings have gained more importance in recent past. Advances in powder and wire production along with developments in thermal spraying techniques have resulted in development of surface coatings with excellent corrosion resistance properties. This paper reviews the performance, developments and applications of thermal spray coatings for high temperature corrosion resistance.
