| 摘 要： | In this paper,the adherence and thermal barrier properties of A12O3-based ceramic metal gradient coating with the method of oxyacetylene-flam-spray are studied. The results show that the physical and chemical compatibilities between the coating and the substrate are improved by adding Cu,Ni/Al and the gradient coating,and to relax thermal stress and interface stress in coat and at the same time to increase adherence property of coating. Besides,the gradient coating has good spalling resistance,erosion resistance to high temperature liquid iron and the effect of thermal barrier properties is remarkable.
