The polarization resistance is Rc for one time constant and Rc + Rct for two-time constants. If Rct follows a Tafel law it is not the case of Rc the coating resistance. Then the polarization resistance does not follow a Tafel law and the results in Table 2 had no meaning.这是我文章中审稿意见,交流阻抗我放了一个两个时间常数的等效电路,然后放了一个Tafel腐蚀电位和腐蚀电流拟合数据表table2
