摘要：
Transient liquid phase bonding of graphite to Ti6Al4V alloy has been conducted with Cu foil, Ti/Cu and Cu/Ti/Cu foils, respectively. A diffusion zone containing Ti-based solid solution and Ti2Cu develops between the bonding zone and Ti6Al4V substrate for all the joints. The bonding zones of joints with Cu foil and Cu/Ti/Cu foils are both composed of TiCu and Ti2Cu. However, the bonding zone of joint with Ti/Cu foils consists of zones I, II and III. Both zones I and III are mainly comprised of TiCu and Ti2Cu, while zone II is a Ti residual zone. The joints with Cu/Ti/Cu foils exhibit the highest shear strength of 17.5 +/- 1.7 MPa due to the most favourable interfacial bonding.
