Abstract

The microstructure and bonding strength of vacuum-brazed C/C composite and C/C composite with inactive AgCu foil are studied. The interface structure of the brazed joint consists of the TC4/Ti₂Cu+Ti(ss)/Ti₂Cu/TiCu/Ag(ss)+Ti₃Cu₄/TiC/C/C composites. The maximum shear strength of the joint is 33 MPa at 880 °C for 10 min and Ti diffusing from TC4 into the filler improves the wettability on the C/C composite. The interface evolution during the brazing process and associated mechanism are discussed.
