摘要：
Field-assisted diffusion bonding applied in the joining of solid electrolyte borosilicate glass, β″-Al2O3, Y2O-ZrO2 to monocrystal silicate and aluminum were proceeded with bonding machine in the assistance of static electric field. TEM, SEM, XRD and other means were applied to investigate and analyze the microstructure of interface. It is supposed that the interfacial area is a model of metal-oxides-ceramic, and the joining mechanism is solid diffusion joining and static electric bonding. The process of ion migration and accumulation under electric field is the most essential factor for the anodic oxidation and interfacial joining. Temperature and voltage are the basic factors of the solid diffusion bonding of interfacial oxidation. And voltage, temperature, pressure and the condition of surface are the most important factors that govern the bonding process.
