在存在 BSA 的情况下，与 r-SBF 的数据相比，icorr 和 Rp 显示出几乎完全相反的趋势。 一般情况下，BSA首先加速纯Zn的腐蚀速度，然后将腐蚀抑制到14 d，除0.5和7 d外，应考虑计算方法的差异。 此外，从极化曲线可以观察到，在 r-SBF 中浸泡的前 6 小时，纯 Zn 仅显示小的钝化区。 然而，在这项工作中存在 BSA 的情况下，0 天和 0.5 天的样品会出现明显的钝化区域。 这种差异意味着 BSA 的快速吸附改变了纯 Zn 在浸泡初期的腐蚀行为。

In the presence of BSA the icorr and Rp show almost completely opposite trends compared with the data for r-SBF. Generally, BSA accelerates the corrosion rate of pure Zn at first and then suppress the corrosion till 14 d except for 0.5 and 7 d.The discrepancy of calculation methods should be taken into consideration. Additionally, from the polarization curves one can observed that in the first 6 h immersion in r-SBF, pure Zn only displays small passivation-like regions. However, in the presence of BSA in this work distinct passivation areas show up for 0 d and 0.5 d samples. This difference implicates that the rapid adsorption of BSA alters the corrosion behavior of pure Zn in the initial of immersion.
