摘要： 通过预置金属粉末的方法实现了5A06铝合金/镀锌钢异种金属涂粉的对接熔钎焊连接,获得了具有熔焊和钎焊双重特征的对接接头.运用扫描电镜(SEM),能谱仪(EDS)及X射线衍射仪(XRD)分析了接头微观结构和成分,并测试了接头力学性能.结果表明:界面处形成了厚度不均的锯齿状金属间化合物层,化合物层由Fe2Al5和FeAl3组成,厚度约2.5~7 μm.在镀锌钢的上表面钎焊界面处,金属间化合物层最厚,其厚度随激光功率的增加而增大.采用预置金属粉末,在合适的焊接参数下,可以控制金属间化合物层厚度最大不超过10 μm,得到具有一定抗拉强度的铝/镀锌钢对接接头.

Abstract: Laser welding-brazing of 5A06 aluminum alloy and galvanized steel sheet with filler powder was carried out. The obtained butt joint exhibited dual characteristics. The interfacial properties and microstructure of the joints examined using Scanning Electron Microscopy (SEM), Energy Dispersive Spectrometer (EDS) and X-ray Diffraction (XRD), and the tensile strength was measured. Results show that a non-uniform intermetallic compound (IMC) with serrated shape is formed at the interfacial layer, which is composed of Fe2Al5 and FeAl3. The thickness of the IMC layer varies from 2.5 ~ 7 μm, and it increases with the laser power. At the top surface of the galvanized steel the IMC layer reaches the thickest. Using this laser welding-brazing method with special filler powder, the IMC thickness can be controlled to less than 10 μm, and butt joints with certain tensile strength can be obtained under appropriate welding parameters.

Key words: metallic materials, aluminum alloy and steel, laser welding-brazing, intermetallic compounds, mechanical property
