Abstract

The present work aims to bond silicon nitride using niobium foils by solid state diffusion bonding, to clarify the reaction behavior at the joint interface. Bonding temperature and time ranged from 1573 to 1773K and 3.6 to 32.4ks, respectively. The resultant interfacial structure was analyzed by SEM, EPMA and XRD. The phase sequence at the interface appears as Si_3N_4/Nb_5Si_3/Nb_2N+Nb/Nb in the case that commercial Nb foils are used. On the other hand, when fine grained films are used, Nb_2N is formed as a layer adjacent to Nb_5Si_3.
