ABSTRACT
The demand for renewable energy sources for power generation has attracted the attention of the research community in the last decade owing to the depletion of fossil fuels and environmental issues. Extensive experimental investigations have been conducted to extract maximum energy from natural resources in the dams and power plants. The coating technologies play a significant role in protecting the components used in power plants. The thermal spraying technique is considered as an effective and economical hard facing method for applying coatings consisting of multilayer stacks on the surface of structural components. However, the latest material development in the form of nano-size scale enhances the material properties like hardness, toughness, and resistance to sliding wear. This is mainly due to reduction in inherent defects and dislocation of grain boundaries. Hence, the deposition of nanostructured material leads to an engineered surface with outstanding coating efficiency. The current study focuses on the high-temperature oxidation behavior of nanostructured coatings deposited by thermal spraying concerning the role of main alloying elements at high temperatures towards oxidation, oxide scale growth, and spallation tendency of coatings.
