摘要	ZG21 Mg alloys exhibit excellent deformation ability at room temperature. However, their corrosion behavior lacks sufficient investigation. The relationship between the second phases and micro-galvanic corrosion of ZG21 Mg alloys has been investigated using Atomic Force Microscopy (AFM), Scanning Kelvin Probe Force Microscopy (SKPFM), and electrochemical measurements. Mg3Zn3Gd2 second phases act as micro-cathodes due to their nobler potential than alpha-Mg matrix. Localized corrosion occurs at cast ZG21, whereas general corrosion occurs at rolled ZG21. The rolled alloy shows better corrosion resistance owing to the relatively more homogeneous distribution and finer second phases.; ZG21 Mg alloys exhibit excellent deformation ability at room temperature.
