采用 Cu 、Sn 、Ti 单质金属粉混合制备了活性钎料，在真空炉中对 CBN 进行了钎焊连接，实现了CBN 与 Q235钢基体的高强度连接。运用 SEM 、EDS 分析了 CBN 与钎料的界面微观组织、元素分布。结果表明：混合金属粉实现了钎料合金化，对 CBN 的润湿性较好，钎料与 CBN 、钢基体发生了界面反应，生成了含 Ti 的化合物，钢基体中的少量 Fe 元素随 Ti 扩散到 CBN 并形成白色块状 TiFe 化合物。

Active filler was mixed using metal powder of Cu , Sn , Ti . With this filler , CBN was brazed in vacuum furnace to realize a high strength connection between CBN and steel substrate of Q235 . The microstructure , distribution of the interface between the elements of CBN and brazing alloy was analyzed by SEM and EDS . The results showed that the metal powder could be alloyed , and had good wettability with CBN . The interfacial reaction occurred among brazing alloy , CBN and steel matrix to generate compounds containing Ti . It was shown that a small amount of Fe in steel substrate diffused into the CBN to form white TiFe compounds in clumps with Ti .
