Abstract

Silicon carbide ceramics were pressureless joined by using Ti foil and Si powder, which generated Ti3SiC2 phase as the interlayer. The phase composition, microstructure and the shear strength were investigated. It was revealed that the SiC assembly after joining at 1500oC showed the high shear strength of 76.2 ± 19.5 MPa. The secondary phase of TiC within the interlayer was expected to contribute to densification improvement of Ti3SiC2 phase and thermal stress reduction.
