摘要
Abstract
An AlSiY diffusion coating was developed by a combined approach of arc ion plating and subsequent diffusion treatment.Oxidation behavior of the coating specimens under 1000℃ and hot corrosion behavior of the coating in Na2SO4＋NaCl salts were tested.X-ray diffractometry（XRD） and scanning electron microscopy（SEM） were used to investigate the phase structures and cross-section images of the coating,respectively.The results indicate that the AlSiY diffusion coating consists of β-NiAl matrix with dispersed precipitates of α-W and CoWSi;the enhanced performance of the AlSiY diffusion coating is related to the β-NiAl matrix in the outer layer,which sustains the formation and repair of alumina scales.关键词
