摘要	Thermal barrier coatings were deposited on the third generation single crystal superalloy DD90. NiCrAlY+NiCoCrAlTaY double-layer bond coatings were prepared by high velocity oxy-fuel spray (HVOF). The ceramic layers of YSZ and MSZ/YSZ structures were prepared by atmospheric plasma spray (APS) technique. The oxidation resistance test results at 1150 degrees C show that the mass gain of YSZ coatings is significantly higher than that of the MSZ coating. After 250 thermal cycles at 1200 degrees C, no obvious phase transition occurs in the two coatings and the sintering resistance of the MSZ coating is improved. TGO of the two coatings mainly consists of Al2O3 and a small number of mixed oxides of spinel structure. The double-layer bond layer reduces the diffusion of Al element into the substrate, whereas the concentration gradient diffusion of Cr element leads to the precipitation of topological close-packed (tcp) phases and the increase in the depth of secondary reaction zone (SRZ).
