Abstract: Provided is a method for fabricating a thermal barrier coating having self-repair and temperature-sensitive functions; the coating material comprises the preparation of a Ni-Co-Fe-Cr-Si-Al-Ti metal sintered mixed material, preparing Er 3+  modified yttria-stabilized zirconia (YSZ) precursor sol, and preparing a SiO 2  mixed La-Ce-Zr-O ceramic composite material; the coating preparation method comprises the use of a supersonic flame spraying process or an explosive spraying process to spray the metal sintered mixed material on the surface of a superalloy to form a bottom layer; then spraying the yttria-stabilized zirconia (YSZ) precursor sol onto the surface of the bottom layer by a liquid plasma spraying process so as to form an intermediate layer; finally, using a plasma spraying process or an explosive spraying process to spray the of SiO 2  mixed La-Ce-Zr-O ceramic composite material on the surface of the intermediate layer so as to form a surface layer. The advantage is that the use of a high-entropy alloy bottom layer can improve the high-temperature resistance and bonding strength of the bottom layer. A temperature-sensitive thermal barrier coating co-doped with rare earth ions is used as the intermediate layer, and the mapping relationship between the luminescence properties of the Er 3+  rare earth element and temperature can be used to monitor in real time the trend of changes of the internal temperature of the coating; SiO 2  repair agent microcapsules compounded with the La-Ce-Zr-O coating are used as the surface layer; if the coating cracks and fails, the microcapsules are broken due to stress. and SiO 2  repair agent flows out; under high-temperature conditions, an oxidation product is generated to fill a certain amount of cracks in the ceramic material, thus achieving a self-repair function.
