Abstract

Joining technologies of ceramics to metals have been advanced in recent few years. There have a lot of difficult problems to be overcome in developing joining techniques. To control the chemistry of interfaces is, of course, one of the big key points. The active metal brazing has been established for solving this problem and gives us high quality of joints. To construct an appropriate interlayer for reducing thermal stress originating from thermal expansion mismatch between a ceramic and a metal is another critical problem. The soft metal interlayer and the soft metal/hard and low expansion metal laminate interlayer are proved to be two of the effective interlayers. The other bonding parameters such as surface roughness of bond face and bonding pressure are also important to get sound as well as strong ceramic/metal joints.
