摘　　要：对Al2O3-SiC-C质浇注料分别进行110℃、300℃和500℃预处理,然后采用喷涂工艺在其表面制备氧化锆涂层,借助光学显微镜和SEM研究氧化锆涂层对Al2O3-SiC-C质浇注料的抗氧化性和抗侵蚀性的影响。研究表明:经300℃预处理,采用喷涂工艺喷涂一次,Al2O3-SiC-C质浇注料的抗氧化性和抗侵蚀性较好。The zirconium coating was prepared with the surface treatment process of spraying,after pretreatment at 110 ℃ 、300 ℃ 、and 500 ℃.The effect of Al2O3-SiC-C castable oxidation resistance and slag resistance for the zirconium coating was studied by scanning electron microscope and optical microscope.The results showed that oxidation resistance and slag resistance of Al2O3-SiC-C self-flow castable matrix was better,when the mareix was pretreated at 300 ℃ and sprayed once.
