Fusion-induced Diffusion Joints of Solidified TiC-TiB2 Ceramic with Stainless Steel and Ti-6Al-4V Alloy Achieved by Combustion Synthesis in high-gravity Field

摘要：

　　By taking combustion synthesis to prepare high-performance TiC-TiB2 composite in high-gravity field,joints of TiC-TiB2 with stainless steel and Ti-6Al-4V alloy were achieved respectively by the introduction of stainless steel and Ti alloy plates at the bottom of combustion system.Instant melting at surface part of stainless steel and Ti alloy,followed by atom diffusion between liquid TiC-TiB2 ceramic and the molten metal was considered a reason for the achievement of the joint.Because of the presence of coarsened Al2O3 inclusions nearby the ceramic,shear strength of joint between the ceramic and stainless steel presented a low value of 120 ± 30 MPa.In contrast,because the joint characterized by constitutional continuous gradient is achieved from the ceramic to Ti alloy,resulting in high shear strength of 650 ± 25 MPa between TiC-TiB2 ceramic and Ti-6Al-4V alloy.
