Abstract

SiC-coated three-dimensional (3D) C/SiC composites were successfully joined with a Ni-Ti-Nb multi-interlayer by spark plasma sintering (SPS). The interfacial microstructure, phase evolution, and mechanical properties of the as-prepared joints were investigated. A sawtooth-like interfacial structure was generated as a result of the non-uniform dissolution behavior of SiC during the joining process. This interfacial structure substantially enhanced the interfacial bonding strength of the composites. The evolution of the interfacial microstructure was correlated with the mechanical properties of the joints. Finally, a reliable joint free of microdefects with a shear strength of 108 ± 5 MPa was obtained by precise tailoring of the interfacial microstructure.
