摘要：
The Al2O3 and ZrO2 composite thermal barrier coating was prepared on the steel 20G substrate by atmospheric plasma spraying technology. Phases constitution, microstructure and element distribution of the coating were studied by X-ray diffraction (XRD), scanning electron microscope (SEM) and electron probe microanalysis (EPMA). And the forming process of cracks and porous were analyzed. The results show that the composite coating are composed of some steady phases such as α-Al2O3 and t-ZrO2. The bonding strength and density are enhanced as Al2O3 and ZrO2 powders are melted together.
