摘要：

Joining of tetragonal zirconia polycristals (TZP) to Ti for a number of potential applications, including biomedical, has been investigated. The ceramic-metal joints were produced by active metal brazing. A Ag-35Cu-1.65Ti filler metal has been used with brazing taking place at 900 degrees C in vacuum during 1-30 minutes hold. Joints with strength matching 60% of the ceramic strength have been realized. The interfacial microstructures were characterised by SEM, EPMA and XRD. Several reaction products with a layered microstructure were formed, including Ti2O followed by Cu-Ti-O compounds at the ceramic side and Cu-Ti intermetallics at the Ti workpiece side. The overall interface microstructure was different when TZP was brazed to itself, yet the reaction product adjacent to the ceramic was a Ti-oxide, TiO.
