Al/Zn-3Al/Al超声波辅助钎焊接头焊合率及显微组织

  • 摘要: 采用固定间隙超声波辅助无钎剂钎焊方法制备了Al/Zn-3Al/Al钎焊接头,并研究了超声振动时间、超声振动功率以及钎焊温度对接头焊合率和显微组织的影响. 结果表明,液相钎料与母材间的冶金结合首先发生在接头的边角处,随着超声振动时间的延长或功率的增加,冶金结合区域逐步向接头的中心蔓延;当超声振动功率高于210 W,超声振动时间长于2 s时,接头能获得优良的焊合率;接头的钎缝层主要由Zn-Al共晶相和α-Al相组成,升高钎焊温度或延长超声振动时间均会增加钎缝层中α-Al相的含量,其机制主要归因于超声空化效应对母材的溶蚀作用.
