Abstract

The ability to join ceramics with and to metals is a limiting aspect of many plans for the future use of both structural and functional ceramics. The distinctive technologically interesting characteristics of ceramics such as hardness or refractoriness are due to the ionicity or covalency of their lattice structures which lack the delocalised electrons that bind together metals. Hence ceramic-metal interfaces can be energetically unfavourable regions of severe electronic discontinuity. Special interfacial chemistries are needed if continuity is to be achieved and high integrity interfaces produced. This paper comments on important chemical effects during brazing and diffusion bonding.
