英文摘要	A multilayer composite coating, comprised of alternating Ni + CrAlYSiHfN sub-layers and AlxN sub-layers, was manufactured by magnetron sputtering. The multilayer is composed of beta-NiAl, alpha-Cr and AlN phases after annealing, and their volume fractions are 72 vol.%, 12 vol.% and 16 vol.%, respectively. Due to doping with nitrides, the CTE of multilayer coating is reduced to around 12.7*10(-6)/K. The lower CIE mismatch allows multilayer coating to exhibit good resistance to oxide scale spalling in thermal cycling at 1100 degrees C. The theta-to-alpha Al2O3 transformation in oxide scale caused a small drop of residual stresses on multilayer coating in initial oxidation stage.
