摘要
采用干湿浸渍实验获得耐候钢的防护性锈层.应用交流阻抗实验方法测试了所得的锈层,建立了等效电路分析数据.结果表明,交流阻抗方法可以有效地分析耐候钢内锈层的性质.干湿浸渍循环实验与交流阻抗方法相结合,可以快速、合理地评价耐候钢耐蚀性能.
The rust layer of a weathering steel was obtained by using dry-wet circle test and then analyzed by Electrochemical Impedance Spectroscopy （EIS） with an established equivalent electrical circuit. The results indicated that the technique of EIS test could be used to analyze characteristics of the inner rust layer of the weathering steel effectively. The combination of dry-wet circle test and EIS test would be applied to evaluate the weathering steel＇s corrosion-resistant performance rapidly and reasonably.
