Laser welding-brazing characteristics of AZ31B/TC4 joint based on electroplated Cu interlayer

  • 摘要: 采用钛表面电镀铜作为中间层,开展镁(AZ31B)/钛(TC4)对接激光填丝熔钎焊,对镁/钛非互溶不反应焊接体系进行调控. 主要研究了激光功率对镁/钛接头焊接质量的影响规律,进一步分析了不同工艺参数条件下镁/钛界面组织及接头力学性能. 结果表明,铜镀层提高了熔融焊丝在母材表面的润湿铺展并卷入到焊缝组织中,随着激光功率的增加,镁/钛界面形成Ti3Al反应层的能力提高,界面结合强度随之提高. 在较高激光功率1 700 W时,接头拉伸载荷最高达到3 085 N,为镁母材的76.2%,而接头在较高激光功率下的断裂模式也由完全界面断裂转变为部分界面断裂.
    Abstract: Electroplated Cu coating was adopted as an interlayer to enhance the welding quality of laser welded-brazed immiscible and nonreactive Mg(AZ31B)/Ti(TC4) dissimilar metals. The influence of laser power on Mg/Ti welding was investigated, and then the interfacial microstructure and joint mechanical properties were analyzed with various welding parameters. The results indicated that Cu coating can significantly promote wetting-spreading ability of molten filler on the base metals. The molten Cu was involved into weld seam and diffused far from the interface. With the laser power inereasing, the tendency of formation of Ti3Al interfacial reaction layer was improved. At the same time the interfacial bonding between Mg and Ti was enhanced. The maximum tensile load of Mg/Cu coated Ti joint was 3 085 N with the laser power of 1 700 W, representing 76.2% joint efficiency with respect to the Mg base metal. With higher laser power, the fracture mode of joint changed into a partial interfacial fracture from a complete interfacial fracture.
