Most applications of ceramics in devices and structures require some type of ceramic-metal joining. Various processes are available for joining. Two most frequently used techniques are liquid phase joining and solid state bonding. This paper describes the mechanisms leading to the formation of high strength bonds and the mechanical behavior of ceramic-metal multimaterials made by solid state bonding. In this process, bonding is achieved through two stages: (a) morphological adaptation of the surfaces to be joined and (b) subsequent formation of bonds: van de Waals interactions, chemical bonds by simple recovery of the molecular orbitals or growth of intermediate phases. From the mechanical point of view, the study of ceramic-metal interfaces has to consider other factors like: interfacial fracture mechanics, residual stresses, modifications, damages and embrittlement of materials near the interface, as well as many physico-chemical aspects. Thus, a complete understanding of ceramic-metal structures requires an overall analysis of properties of bulk materials and interfaces in the joining area.
