Abstract  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.
Key words:  active metal brazing      Ti foil      joining interface      Zirconia      denaturizing layer      bonding state
