The composite-gradient high temperature abradable sealing coating was prepared by choosing the right spray parameters and the ratio of composite spray materials on the Atmosphere Plasma Spray （APS） system according to the standard APS routine. The microstructure, the EDS micro-zone chemical composites, the oxidation resistance of coating microstructures and the oxidation weight gains curve of the coating were investigated. The results show that the microstructure and the properties of the coating match the relative standard and meet the requirements of the high temperature abradable sealing, and the coating has been put into practice up to now.
