图 6a 显示了浸入 AP 不同时间后 Zn 样品的 XRD 图案。 除了Zn基体的峰外,所有样品的XRD谱上均未观察到衍射峰。这可以归因于腐蚀产物具有非晶结构。
Fig. 6a shows XRD patterns for Zn samples after immersion in AP for various periods. In addition to the peaks from Zn substrates, no more diffraction peaks can be observed on the XRD spectra of all samples. This can be ascribed to that the corrosion products have amorphous structures.
