Materials factors affecting joining of silicon nitride ceramicsFunded under: JRC-ADVMAT 1C
This paper describes the beneficial roles played by the reactive metals Cr and Ti in the brazing and diffusion bonding of a range of silicon nitride ceramics. Ti and Cr, present as alloying elements in brazes or diffusion bonding foils, segregate to the ceramic/metal interface and promote joining by the formation of nitride reaction product layers. Results are presented and analysed for Ag, Cu and Ni brazes and for Ni diffusion bonding foils. The influence of reactive species concentration, surface modification of the ceramic and environment on the microstructure and mechanical integrity of joints is described.
