采用B2O3，Bi2O3，TiO2混合钎料，通过钎焊连接方法实现K9玻璃与纯Ti在低温下的连接；通过光学显微镜和SEM等方法研究钎焊时间对接头界面组织及性能的影响. 结果表明，当B2O3:Bi2O3:TiO2成分为5:4:1时，钎焊温度为650 ℃，保温时间分别为60，80和100 min时，抗剪强度分别为11.5，15.1和12.1 MPa. K9玻璃/钎料结合致密，且存在反应层，而纯Ti/钎料侧界面平直，没有明显的过渡层和熔解现象. 接头断裂一种为完全断裂在金属与钎焊层的脆性断裂，抗剪强度为11.5 MPa；另一种为部分断裂在金属与钎焊界面处，部分断裂在玻璃侧的混合断裂，混合断裂接头抗剪强度最高为16.7 MPa.

The mixed brazing-filler-material of B2O3, Bi2O3 and TiO2 was used to realize the joining of K9 glass and pure Ti at low temperature through brazing. The effects of holding time on the microstructure and properties of the joints were studied by optical microscopy and SEM. The results showed that the shear strength of joints was 11.5 MPa, 15.1 MPa and 12.1 MPa when the composition of B2O3:Bi2O3:TiO2 was 5:4:1 and the brazing temperature was 650℃, as the holding time was 60, 80 and 100 min, respectively. K9 glass/brazing-filler-material was densely bonded with a reaction layer, while the pure Ti/brazing-filler-material side interface was straight with no obvious transition layer and dissolution phenomenon. One kind of joint fracture was brittle fracture completely in the metal and brazing layer, the shear strength was 11.5 MPa. The other was a mixed brittle fracture which happened partially in the metal and brazing layer and partially in the glass-side. The maximum shear strength of the joint with mixed brittle fracture was 16.7 MPa.
