摘　　要：用落球试验、扫描电镜、X射线衍射、电化学测试等方法对用热熔敷法和火焰喷熔法制取的玻璃涂层性能进行了研究。结果表明,两种方法得到的玻璃涂层表面质量好,主要由玻璃相组成,有少量晶相析出;火焰喷熔涂层与金属的作用剧烈、反应充分、形成的过渡层宽,密着强度较热熔敷涂层的高,且后者的底釉层与面釉层之间存在界面夹层,影响面釉层的密着;热熔敷涂层与基体反应轻微,耐蚀性好,而火焰喷熔涂层与基体反应剧烈,耐蚀性差。The properties of glass coating prepared by heat deposited method and flame spraying method were studied in this paper using falling ball experiment, SEM, X-ray diffraction and electrochemistry tests etc. The results showed that the surface quality of glass coating was good and the micro structure of coating surface was mainly composed of glass phase with a little crystalline phase. The flame sprayed coating reacted severely with metal, produced wide transition layer and its adhesive strength was higher than that of heat deposited coating. Moreover, between the bottom glaze layer and surface glaze layer of the latter appeared interfacial sandwich layer, which can influence the adhesive strength of glaze layer. The heat deposited coating reacted lightly with matrix metal and its anti-corrosion property was good. The flame sprayed coating reacted violently with matrix metal and its anti-corrosion property became worse.
