摘  要:用XRD、EPMA,IMA,XPS,AES等测试手段,对使用钛箔活性金属法连接氧化锆陶瓷和不锈钢时结合界面的反应行为进行了研究结果表明:ZrO2中的O同界面附近的Ti发生反应生成TiO反应相。同时,结合界面附近的ZrO2引起变质现象,其变质层中O的含量降低。Reaction behaviour of the interface between ZrO2 and Ti in loining zirconia ceramics and stainless steel with Ti foil as active metal was studied by means of EPMA, XRD, IMA, XPS and AES. The results show that O diffused from the zirconia into the Ti active metal zone to produce TiO. The amount of O in the denaturizing layer was found to decrease. The bonding state of Zr in the denaturizing layer changed from Zr4+ to Zr2+. At the same time, the diffusions of Ti and Zr were found in the zirconia near the interface between zirconia and Ti.
