Surface analysis of the ceramic-steel interface joined with an active metal and brazing metal foils was carried out by SEM, TEM, EDX and XPS. The analyzed specimen was the sintered silicon nitride joined to SNCM steel by Ti metal and Ag/Cu (72/28) brazing metal. (1) Two reaction layers were produced between Si_3N_4 and braze. (2) A reaction layer facing Si_3N_4(layer I) was about 300 nm thick and composed mainly of titanium nitride (TiN) . (3) The other reaction layer (layer II) between layer I and the braze was composed of titanium nitride (TiN) and silicide (Ti_5Si_3). The thickness of this layer was about 3 μm.
