Abstract:With the development of advanced aero-engine propulsion engine towards high propulsion and long service life, the traditional yttria stabilized zirconia (6-8YSZ) thermal barrier coating system containing 6-8wt.% yttria stabilized zirconia (6-zirconia) thermal barrier coating will undergo high temperature phase transformation when the service temperature is above 1200 ℃ , resulting in thermal stress between coatings and spalling failure of the coating. Therefore, it is urgent to introduce the new material system and improve the coating structure. This paper introduces the development history of traditional YSZ and describes the research progress and development prospect of ceramic materials such as rare earth oxide stabilized zirconia, perovskite structure and rare earth zirconate (A 2 Zr 2 O 7 ) pyrochlore structure, and analyzes the research status and future development trend of new hafnium oxide matrix ceramic thermal barrier coating system and high entropy material system coating. Finally, the problems and development of new thermal barrier coating materials are summarized and prospected.
