摘要	A gradient NiCoCrAlSiY coating consisting of Al-enriched outer zone and Cr-enriched internal zone was prepared using arc ion plating method and subsequent annealing treatment. Isothermal oxidations were performed at 1000 degrees C and 1100 degrees C in static air. The results confirmed an enhanced performance for the gradient NiCoCrAISiY coating in contrast to the conventional NiCoCrAlSiY, due to the high-Al content and the in-situ Cr(Re, W)-rich diffusion barrier which exists in the gradient coating. The degradation mechanisms for the two coatings and the formation mechanism for the diffusion barrier are discussed. (C) 2009 Elsevier Ltd. All rights reserved.
