摘　　要：借助差热分析研究镍基高温合金/陶瓷型壳的界面反应,分别从热力学和动力学的角度分析出镍基高温合金叶片在生产过程中陶瓷型壳所需的最佳面层涂料是CoAl2O4。With the aid of DTA method the reaction between ceramic mold and Ni-based high temperature alloy was researched. Based on the thermodynamic and kinetics analyse of ceramic mold respectively, it was concluded that in production the best plus material for Ni-based high temperature alloy turbine blade was CoAl2O4.
