摘要	Cr2AlC transition layer between the NiCrAlY coating and K417G superalloy was prepared to improve oxidation resistance of conventional NiCrAlY coating. Long-term cyclic oxidation was conducted at 1000 degrees C. Cr2AlC transition layer decomposed to Cr7C3 after annealing and further transformed to thermodynamically more stable continuous Cr23C6 during subsequent oxidation. Continuous Cr23C6 effectively blocked diffusion between NiCrAlY coating and substrate. Cr2AlC transition layer also supplied additional Al for NiCrAlY coating, greatly extended service life of the NiCrAlY coating. Furthermore, Cr2AlC, Cr23C6 and Cr7C3 were thermally matched to substrate and coating, avoiding coating spallation during cyclic oxidation.
