摘要	Detonation gun spraying (DS) was used to deposit NiCrAlTaY oxidation resistant coating on a single crystal Ni-base superalloy. A fundamental study was carried out on the microstructure, surface hardness and adhesion strength of DS NiCrAlTaY coating by means of XRD, SEM and EDS. The experimental results show the DS NiCrAlTaY coating composes of gamma - Ni, gamma' - Ni3Al, beta - NiAl and the oxidation product alpha - Al2O3 during spraying, which disperses on the splat boundaries. Columnar crystal structure is formed in the splats under the large thermal gradient. Porosity of the as-sprayed coating contains the residual,air. Both the hardness and adhesion strength of DS NiCrAlY coating are high.
