摘要: 用交流阻抗技术在宽频率范围(0.01Hz-65kHz)内测定了六种有机涂层/碳钢在3%氯化钠溶液中的频谱图。用不同的等效电路解释了不同涂层体系的频谱行为,讨论了不同涂层的保护性能并分析了层下金属的腐蚀过程。

Abstract：AC impedance techniques in a broad frequency range(0.01Hz-65kHz) are applied to some organic coatings on mild steel in 3% sodium chloride solution.The coatings studied include commercial emulsion paint,primers and electrophoretic ones.Models for the impedance behavior have been developed for different coating systems,and methods for the analysis of experimental impedance diagrams in terms of coating and interface properties and their changes during exposure to corrosive environments are discussed,and an assessment of the behavior of these coatings is made in the light of the analysis.
