  • About author:Liu Shijie, born in 2001, is studying in Luoyang Institute of Science and Technology. He is mainly engaged in the research of ultra-high temperature ceramic coatings.

Abstract: Ultra-high temperature ceramic coatings have ultra-high melting points, excellent mechanical properties and high temperature ablation resistance. These unique performance combinations turn it into a promising material for use in extreme environment structures in rockets and hypersonic vehicles, particularly nozzles, leading edges and engine components. In this paper, various preparation methods of ultra-high temperature ceramic coatings were reviewed, including plasma spraying, chemical vapor deposition, pack cementation, slurry sintering, hot pressing and their research progress. Meanwhile, some new preparation methods of high temperature coatings, such as ion beam deposition, ultrasonic spraying, metal organic frame work coating, and magnetron sputtering, were introduced. The development trend of ultra-high temperature coatings was prospected as well.

Key words: ultra-high temperature coating, preparation process, development prospect
