摘要	A gradient NiCoCrAlYSi coating was prepared by a combined method of arc ion plating and subsequent diffusion treatment. The microstructure of the gradient coating was investigated in the as-annealed condition and after oxidation at 1000 degrees C. During the oxidation, an in situ diffusion barrier composed of Cr(W)-rich sigma phases was formed in the interdiffusion zone, resulting in an effective inhibition of inward diffusion of Al. The formation of the in situ diffusion barrier layer is also discussed. (C) 2010 Elsevier Ltd. All rights reserved.
