The aircraft engine is considered the “heart” of the aircraft. The development of advanced aircraft engines focuses on achieving a high thrust-to-weight ratio,high efficiency,low fuel consumption,and extended operational life. High-temperature functional coatings,such as thermal barrier coatings(TBCs),thermal/environmental barrier composite coatings(T/EBCs),and high-temperature stealth coatings,are applied to critical hot-end components of aircraft engines. These coatings play a significant role in enhancing the service performance,operational life,safety and reliability of the engine. Taking TBCs,T/EBCs,and high-temperature stealth coatings as examples,this paper provides a systematic overview of recent research progress in the design of high-temperature functional coating materials,coating preparation science and technology,and coating performance evaluation and characterization,both domestically and internationally,with a specific focus on the advancements made at Beihang University. Furthermore,challenges and development trends faced by new high-temperature functional coatings of advanced aircraft engines in the future are also discussed. In the future,the research focus of advanced high-temperature functional coatings will shift toward multifunctional composite coatings,enhanced adaptability to extreme environments,and improved process compatibility.
