Abstract
Coal-fired thermal power plants are the prime source of electricity worldwide. The higher operating temperature and pressure of these power plants cause high-temperature oxidation and corrosion of the boiler materials used in these power plants. Various advanced materials have been developed to resist these degradations, but individual advanced materials were found insufficient to resist such degradations for longer. It is accomplished by providing an additional protective coating of the oxidation-resistant material over the surface of the metallic component having desired mechanical properties. Researchers have investigated the high-temperature performances of various base materials and coatings combinations. Different coating techniques have been used to deposit the coatings, including electroplating, thermal spray coating, physical vapor deposition, chemical vapor deposition, etc. Among all these methods, the thermal spray technique is reported to be a cost-effective method to deposit coatings with good mechanical and microstructural properties. In this paper, a brief review of the literature on the high-temperature oxidation performance of thermally sprayed boiler tube materials has been presented and discussed.
