应用电化学阻抗谱（EIS）来评估覆盖有薄电解质膜的钢的腐蚀速率。双电极电池由一对嵌入环氧树脂中的相同钢板组成，用于薄电解质膜下的 EIS 测量。采用传输线型等效电路来描述 EIS 行为。使用该方法，成功地估计了不均匀电流分布下的电荷转移电阻。该技术用于估计电解质膜厚度在 5 μm 至 1 mm 范围内的钢的腐蚀速率。
Electrochemical impedance spectroscopy (EIS) was applied to evaluate corrosion rates of steels covered with a thin electrolyte film. A two-electrode cell consisting of a pair of identical steel plates embedded in epoxy resin was used for the EIS measurements under the thin electrolyte film. A transmission line type equivalent circuit was employed to describe the EIS behavior. Using this method, a charge transfer resistance was successfully estimated under uneven current distributions. This technique was applied to estimate the corrosion rates of steels under electrolyte film thickness in a range of 5 μm to 1 mm.
