- 摘要:
- 将钢基体在熔融的纯锌、铝锌合金中热浸镀不同时间后浇注铝合金，获得钢/铝复合铸件。 研究热浸镀时
间、热浸镀合金种类对钢/铝复合铸件中钢/铝界面显微组织和力学性能的影响。 结果表明，钢热浸镀纯锌、铝锌合金后，
钢/铝界面处均形成了靠近钢基体的 Fe2Al5 连续相层和靠近铝基体的 FeAl3 弥散颗粒相层。 随着热浸镀时间的延长，金
属间化合物层厚度不断增大。 钢热浸镀纯锌后，界面剪切强度最大为 64.6 MPa；钢热浸镀铝锌合金后，界面剪切强度最
大为 83.2 MPa。
The steel matrix was hot dipped in molten pure zinc and Al-Zn alloy for different times, and then aluminum alloy was poured to obtain the steel/aluminum composite casting. The effects of hot dip time and hot dip alloy on the microstructure and mechanical properties of steel/aluminum interface in steel/aluminum composite castings were studied. The results show that Fe2Al5 continuous phase layer and FeAl3 dispersed particle phase layer are formed at the interface between steel and aluminum after hot dip plating of pure zinc and Al-Zn alloy. The thickness of intermetallic compound layer increases with the extension of hot dip time. The maximum interfacial shear strength of steel is 64.6 MPa after hot dip zinc plating. The maximum interfacial shear strength is 83.2 MPa after hot dip Al-Zn alloy.
