Abstract:Yttria-stabilized zirconia (YSZ) thermal barrier coatings (TBCs) play a central role in the thermal protection of turbine engines. However, with the advancement of aerospace technology and the challenges of higher temperatures, the high-temperature phase transformation issue of YSZ has limited its application. Therefore, developing a new generation of TBCs with high melting points, structural stability, and excellent thermal performance is particularly crucial. Perovskite thermal materials, with their high melting points, structural stability, and tunable thermal properties, have become the new focus of TBCs research. This review outlines the advantages, research hotspots, and preparation techniques of perovskite TBCs from the dimensions of material types and performance regulation, and looks forward to their future development.
