Abstract

Brazing SiC and TC4 involves excessive Ti diffused from TC4 and high residual stress in the joint. In order to achieve a high-quality joint between SiC and TC4, a new interlayer braided by short fibers in three dimensions (3D-SiO₂-fiber) was introduced to assist in brazing. The 3D-SiO₂-fiber, with loose and porous structure, can guarantee abundant SiO₂ fibers evenly distribute in the joint. Furthermore, extensive Ti element was consumed by SiO₂ fibers. Then enormously and uniformly distributed TiSi₂, TiCu₂, TiSi and α-Ti particles were formed at the joint. Finally, residual stress was released and the shear strength of the joint increased to 40 MPa.
