The invention discloses a heat barrier composite cladding layer which consists of a MCrAlY alloy adhesive layer, a NiAl alloy barrier layer, a ZrO2-CeO2 ceramic layer and an Al2O3 protective layer; the NiAl alloy barrier layer is arranged between the MCrAlY alloy adhesive layer and the ZrO2-CeO2 ceramic layer, and the Al2O3 protective layer is arranged on the surface of the ZrO2-CeO2 ceramic layer. The invention adopts a preparation process integrated with electrophoretic deposition, high-speed electrical spray-plating and plasma arc plating layer scanning, and has the advantages of simple operation method, quite low preparation cost, capability of realizing industrialized production and the like, and the prepared heat barrier composite cladding layer also has the advantages of low heat conductivity, low roughness of the cladding layer surface, high integration strength of the cladding layer and the matrix, good hot corrosion resistance performance, good hot oxidation resistance performance and the like, solves the difficulties of poor high-temperature oxidation resistance and high-temperature corrosion resistance of high temperature resistant parts, and prolongs the service life of the high temperature resistant parts.
