  Electrical sialon and alloy tool steel (SKS 3) were braze with an active brazing metal of Ag-Cu-Ti in a vacuum for the purpose of making a strong bonding. Relations between the microstructure of brazing metal, bonding strength, brazing temperature and holding time were studied. Relation between the thickness of brazing metal and the bonding strength was also studied. The effects of stress relaxation by heat treatment of bonds on the bonding strength were studied. Electrical sialon surface was roughned by etching using HF/HNO<sub>3</sub>, and the sialon was brazed. The effect of surface treatment on the bonding strangth was also considered. There is an optimum thickness of brazing metal to obtain a high bonding strength. Deposition of titanium at boundaries between the brazing metal and electrical sialon and between the brazing metal and SKS 3 increased with increasing bonding temperature and holding time. The titanium enriched diffusion layer was formed at the interface between brazing metal and electrical sialon. Stress relaxation by heat treatment of bonds was very effective to increase the bonding strength. A maximum bonding strength over 400 MPa was obtained.
