| 摘 要： | 在1．8ks，1073K－1173K条件下对Al2O3/(Ag72Cu28)97Ti3/Ti-6Al-4V进行了钎焊试验。通过扫描电镜、波谱、能谱、X射线衍射界面结构进行了分析。小于1123K的界面结构为Al2O3/Cu2Ti4O/Cu4Ti3/Ag-Cu共晶＋富Ag相＋Ti固溶体；1173K的界面结构为Al2O3/Cu3TiO5 CuAl2O4/Cu4Ti3/富Ag相。采用拉剪试验测试了接头剪切强度。在1．8ks,1123K时剪切强度最高达到189MPa,大于或小于1123K接头强度呈下降趋势。

| Abstract: | The Al_2O_3 ceramics was bonded with Ti-6Al-4V using (Ag_ 72Cu_ 28)_ 97Ti_3 as filler metal under the conditions of 1 073 k~1 173 K and 18 ks. The interface structure and formation mechanism of joints were investigated by scanning electron microscopy (SEM), X-ray diffraction (XRD) and energy dispersive spectroscopy (EDS). It was found that the interface structure of diffusion-bonded joints is Al_2O_3/Cu_2Ti_4O/Cu_4Ti_3/Ag-Cu eutectic+rich Ag phase+Ti soild solution for bonding temperature below 1 123 K. For bonding temperature of 1 173 K, the interface structure is Al_2O_3/Cu_3TiO_5+CuAl_2O_4/Cu_4Ti_3/rich Ag phase. Strength of the Al_2O_3/(Ag_ 72Cu_ 28)_ 97Ti_3/Nb joint reaches 189 MPa for bonding temperature of 1 123 K and 18 ks. The lower bonding temperature, or the higher bonding temperature, the lower strength of joints. |
