Ceramic/metal reactions and microstructures in ceramic joints
Achieving local chemical equilibration of interfaces between disparate ceramics and metals requires chemical reactions to occur but experience shows that only certain reactions are beneficial and that their progress must be controlled if useful interfaces are to be fabricated. The progress of chemical reactions can affect every stage of the formation of a synthetic interface from the initial achievement of contact, through the development of a stable chemistry and microstructure to the optimization of mechanical properties. This paper provides an overview of our efforts to understand and optimize such effects in order to promote our ability to fabricate ceramic/metal interfaces, drawing on our experience of the brazing and diffusion bonding of Al(2)O(3), Si(3)N(4) and ZrO(2).
