In the thermal power plant, various conventional steels are used to manufacture boiler components. Due to high operating temperature of these boilers, these conventional steels are unable to resist hot corrosion. In recent years researchers have used various techniques to resist hot corrosion out of these techniques, thermal spray coating process have gained lot of interest due to the ease of coating, low operating cost, and various other advantages. With these coating processes a thin layer of coating material is developed over steel alloys surface which creates hindrance to penetration of corroding element and hereby reduce corrosion. This paper is an attempt to present a comprehension the study related to hot corrosion of thermal spray coating on boiler steels at high temperatures.
