This paper reviews recent achievements in high-temperature oxidation, summarizes the characteristics and preparation methods of high-entropy alloys in high-temperature oxidation environments, explains the reasons for their oxidation resistance, and introduces current research and application prospects.
High-temperature oxidation is a common failure in high-temperature environments, which widely occur in aircraft engines and aerospace thrusters; as a result, the development of anti-high-temperature oxidation materials has been pursued. Ni-based alloys are a common high-temperature material; however, they are too expensive. High-entropy alloys are alternatives for the anti-oxidation property at high temperatures because of their special structure and properties. The recent achievements of high-temperature oxidation are reviewed in this paper. The high-temperature oxidation environment, temperature, phase structure, alloy elements, and preparation methods of high-entropy alloys are summarized. The reason why high-entropy alloys have anti-oxidation ability at high temperatures is illuminated. Current research, material selection, and application prospects of high-temperature oxidation are introduced.
