摘      要：An AlSiY coating and two MCrAlY+AlSiY composite coatings with different thickness of MCrAlY interlayer were prepared by arc ion plating(AIP)and vacuum *** isothermal oxidation behavior of coatings at 1100℃ for 300 h was also investigated to characterize the microstructure evolution of coatings during *** composite coatings exhibited a better high-temperature oxidation resistance at 1100℃ .The reason is that the addition of MCrAlY layer can greatly contribute to prevent the diffusion of refractory elements to the outer *** inhibition of Al inward diffusion can be much stronger,as the Si content increases in the outer layer during annealing.
