The invention relates to a preparation method for a sintering resistant thermal barrier ceramic coating structure. The method includes: preparation of electrophoretic deposition turbid liquid, preparation of an electrophoretic coating, preparation of a phase inversion coating slurry, preparation of a phase inversion coating, sintering and other steps. According to the nonsolvent-induced phase separation principle and impregnation method, a porous ceramic coating with an asymmetric structure is prepared on the surface of high temperature alloy, the coating is sintered under air and argon atmosphere in two steps in the coating sintering, and a thermal barrier coating with an asymmetric structure is obtained. Compared with the prior art, the thermal barrier coating prepared by the method provided by the invention has the characteristics of simple process, stable microstructure, good sintering resistance and good thermal shock resistance, the method can prepare coatings on complex shape and asymmetric geometric surfaces, and is easy for mass industrial production. Compared with the prior art, the invention has a lot of advantages.
