Joining of alumina ceramics and nickel alloy
Joining of alumina ceramics to nickel alloy was made using the various types of Ag-Cu-Ti brazing filler metal. Ti-containing brazing filler metal was produced by physical vapor deposition (PVD) method on the joining area of the alumina ceramics. The joinability of the brazing filler metal was estimated by its mechanical properties. And the composition and structure of the ceramic-metal bond zone in the alumina ceramics-nickel alloy joints were analyzed by SEM, EPMA and X-ray diffraction examinations. Some of brazing filler metal achieved the highest shear strength 100 MPa at room temperature. The elemental distributions of the interface between alumina ceramics and Ag-Cu-Ti brazing filler metal was shown to form the reaction layer consisting titanium oxide.
