Abstract: The life of the components operating under various high-temperature environments decreases due to the activation of different failure mechanisms. High-temperature oxidation and erosion are the two prominent mechanisms that lead to the degradation of materials, resulting in the premature failure of the components. This paper has emphasized the failure and performance analysis of nickel-based coatings formulated by using different thermal spraying techniques. Nickel-based coatings like Ni–Cr, Ni3Al, Alloy-718, NiCrAlY, NiCrBSi and Ni-based composite coatings showed excellent resistance against the high-temperature conditions. This study helps to select specific thermal spray techniques and coating composition against high-temperature erosion and oxidation conditions.
