As ceramics capture more industrial applications, the need increases for an economical process for bonding ceramics to themselves and to metals. In some cases, bonding permits the advantages of both materials to be combined in a single assembly. In many other cases, a ceramic-metal bond represents the only way to fully exploit the technical advantages of ceramics.
Complicating the process of ceramic-metal brazing are differences in the materials' properties-their coefficients of thermal expansion in particular-and differences in the way they're wet by molten brazing alloys.
In conventional technology, metallized ceramics are brazed using Fe-Ni and ...
