摘要:

围绕涂层的电化学阻抗、吸水率、附着力研究了一种环氧耐蚀涂层在NaCl溶液中的劣化行为。结果表明涂层浸泡至5350 h后依然具有良好的保护性能，涂层电化学阻抗、吸水率和附着力的变化趋势存在着相关性，电解质溶液与树脂材料的物理/化学反应可能是涂层劣化的主要机制，温度是涂层劣化的重要影响因素，涂层厚度的影响作用不明显。

关键词 ：环氧涂层, 电化学阻抗谱, 吸水率, 附着力

Abstract：

A study was conducted on the degradation behavior of an epoxy corrosion-resistant coating in NaCl solution, focusing on the electrochemical impedance, water absorption, and adhesion of the coating. The results indicated that the coating still exhibits good protective performance after immersion for 5350 h. Meanwhile, a correlation between the changes in electrochemical impedance, water absorption, and adhesion of the coating was observed. The physical/chemical reaction between the electrolyte solution and the resin material might be the main mechanism of the coating degradation, with temperature being a significant influencing factor and the effect of coating thickness being less apparent.

Key words： epoxy coating electrochemical impedance spectroscopy water absorption adhesion
