将钛合金、Ti基非晶活性钎料和陶瓷按三明治结构进行装配,并将装配好的试样放入真空钎焊炉中进行钎焊,对钎焊接头的微观组织和力学性能进行测试分析。结果表明:钎焊接头包括五个区域,从TC4侧到陶瓷侧依次为:TC4钛合金区、钛合金侧反应区、中间的镶嵌结构区、陶瓷侧反应层区、Si C陶瓷区;钎焊接头剪切强度和反应层的厚度密切相关,反应层过厚或过薄均会降低接头强度。因此,合理控制反应层厚度是能否得到高强度钎焊接头的关键所在。
The titanium alloy, Ti-based amorphous active brazing filler metal and ceramic are assembled according to a sandwich structure, and the assembled sample is put into a vacuum brazing furnace for brazing, and the microstructure and mechanical properties of the brazed joint are tested and analyzed . The results show that the brazed joint consists of five regions, from TC4 side to ceramic side, the order of TC4 titanium alloy, titanium alloy side reaction zone, middle mosaic structure zone, ceramic side reaction zone and Si C ceramic zone; brazing Joint shear strength and the thickness of the reaction layer is closely related to the reaction layer is too thick or too thin will reduce the joint strength. Therefore, the reasonable control of the thickness of the reaction layer is the key to the availability of high-strength brazed joints.
