Abstract

Welding of C f / SiC to Ni-based superalloy has been realized using Cu/W/Cu/W/Cu multiple interlayers. The bending strength of the joints has been improved by using the active metallic filler contacted with C f / SiC . The strength of the joints is remarkably affected by the welding temperature. The maximum value 102.1 MPa has been obtained at 970°C (dwell time: 10 min., welding pressure: 34.3 MPa). Microstructural studies were also conducted.
