锌和锌-(0.1-1.4)锂合金浸泡1天后的XPS结果如图10所示。根据光谱和元素分析(图10b),锌-(0.1-1.4)锂合金上的腐蚀产物中的元素非常相似,即锌、C、Li和O。随着材料中Li含量的增加,腐蚀产物中Li的原子含量(t.%)从3.4%的增加到19.4%,同时锌从25.4%的下降到1.0%的。锌-(0.8-1.4)锂合金中的Li 1s峰较强,表示其腐蚀产品含有大量富含锂的产物。
The XPS results of Zn and Zn-(0.1–1.4)Li alloys after 1 day immersion are presented in Fig. 10. According to the survey spectra (Fig. 10a) and the elemental analysis (Fig. 10b), elements in the corrosion products on Zn-(0.1–1.4)Li alloys are quite similar, which are Zn, C, Li and O. With increasing Li content in the materials, atomic percentage (at.%) of Li in the corrosion products increases from 3.4 at.% to 19.4 at.%, meanwhile Zn decreases from 25.4 at.% to 1.0 at.%. Li 1 s peaks of Zn-(0.8–1.4)Li alloys are strong (Fig. 10c), signifying their corrosion products contains considerable amount of Li-rich products.
