为了实现Al-7wt% Si合金（或纯Al）铸件与低碳钢镶件之间良好的冶金结合，开发了一种以热浸Zn-Al合金工艺为特征的新型复合加工技术，并研究了结合区的组织和性能变化。高压扭转（HPT）。在Zn-2.2wt%Al合金镀液中热浸镀锌时，钢表面形成了一层较厚的Al 5 Fe 2 Znx相，阻碍了Fe-Zn化合物层的形成，导致镀层中形成了弥散分布的Al 3FeZnx相。在复合铸造过程中，在Al-Si合金（或Al）/镀锌钢反应偶界面结合区观察到复杂的界面反应，形成Al-Fe-Si-Zn（或Al-Fe-Zn）相。结果表明，HPT工艺在Al/渗铝钢界面的Al-Fe相层（由Al 5 Fe 2和Al 3Fe相组成）中产生了大量裂纹。出乎意料的是，Al/镀锌钢界面区显示出良好的塑性。除铝/镀锌钢界面区外，界面区和基体的显微硬度在HPT处理后均有所增加。
A new composite processing technology characterized by hot-dip Zn–Al alloy process was developed to achieve a sound metallurgical bonding between Al–7 wt% Si alloy (or pure Al) castings and low-carbon steel inserts, and the variations of microstructure and property of the bonding zone were investigated under high-pressure torsion (HPT). During hot-dipping in a Zn–2.2 wt% Al alloy bath, a thick Al5Fe2Znxphase layer was formed on the steel surface and retarded the formation of Fe–Zn compound layers, resulting in the formation of a dispersed Al3FeZnxphase in zinc coating. During the composite casting process, complex interface reactions were observed for the Al–Fe–Si–Zn (or Al–Fe–Zn) phases formation in the interfacial bonding zone of Al–Si alloy (or Al)/galvanized steel reaction couple. In addition, the results show that the HPT process generates a number of cracks in the Al–Fe phase layers (consisting of Al5Fe2and Al3Fe phases) of the Al/aluminized steel interface. Unexpectedly, the Al/galvanized steel interface zone shows a good plastic property. Beside the Al/galvanized steel interface zone, the microhardnesses of both the interface zone and substrates increased after the HPT process.
