SiC CERAMIC WAS JOINED TO ITSELF USING ACTIVE brazing alloys like Ti in shape of sheet filler of Ag-cu and Ti-6AI -4V. This operation is occurred in an inert gas furnace interfacial microstructure studied with scanning electron microscopy and X-ray diffraction variation of electrical specific resistance measured by 4 pin astute multimeter and strength of these joint was measured by fracture shear loading this joint is happened at 900 c and upper temperature with 90 minutes and upper time electrical specific resistance goes upper with joint in low temperature & time but this variation is very little . the microstructure showed and excellent bonding at the interfaces. the data showed also that the joining of the SiC decreases with increasing temperature and time.
