Abstract

Hot corrosion is a major problem in engines, steam generators, steam turbine and thermal power plants. The coating is one of the effective methods to reduce hot corrosion. However, better understanding of the hot corrosion performance of thermal spray coating on a different substrate at different temperature and environment, is required to reduce maximum hot corrosion. This paper summarizes the behavior of Ni, Co, Fe, and metal oxide based coating in the simulated boiler environment. The consolidated results of coating properties such as coating hardness, porosity, thickness and parabolic constant has also been detailed with emphasis on corrosion and its mechanism.
