图 11 提供了在去除腐蚀产物后浸泡 48 小时和 336 小时的纯 Zn 的代表性 SEM 图像，以揭示下面的腐蚀侵蚀。 在不同的浸泡间隔后，Zn 样品表现出均匀的腐蚀，除抛光过程中产生的浅划痕外，未检测到明显的局部腐蚀坑。

Fig. 11 provides representative SEM images of pure Zn immersed for 48 h and 336 h after removal of the corrosion products to unveil the underneath corrosion attack. After different immersion intervals, Zn samples showed uniform corrosion and no obvious localized corrosion pits were detected, except shallow scratches caused by the polishing procedure.
