An AlSiY diffusion coating was developed by a combined approach of arc ion plating and subsequent diffusion treatment. Cyclic and isothermal oxidation behaviour of the coating specimens was tested in a muffle furnace at 1000 degrees C and 1100 degrees C. The results confirmed an enhanced performance of the diffusion coating due to the presence of beta-NiAl enriched outer layer. The microstructure change and the oxidation behaviour of the diffusion coating are discussed. (c) 2009 Elsevier Ltd. All rights reserved.
