摘要	The oxidation behaviour of a fourth-generation single-crystal superalloy without coating and with two types of MCrAlY coatings at 1140 degrees C was studied. The results showed that both coatings greatly improved the oxidation resistance of the superalloy, and the addition of Hf further improved the oxidation resistance by pinning the oxide layer into the coating. Before and after oxidation, obvious Cr and Al interdiffusion was detected. Inward Cr diffusion induces the precipitation of a topologically close-packed phase, while the diffusion of Al affects the structure of the gamma/gamma' phase, the solubility of refractory elements, and the formation of an interdiffusion zone.
