摘要
[目的]船舶表面使用涂层涂覆是常见的船舶防腐方法,涂层防腐性能的好坏直接反映船舶表面的腐蚀程度。尽管涂层涂覆作为船舶上有效的防腐技术已经应用了几十年,但始终缺少对涂层防腐性能进行快速有效检测的方法。[方法]通过建立合理的涂层体系等效电路模型,采用交流阻抗检测技术对试验涂层进行盐雾老化和紫外老化涂层性能试验,并利用Matlab数据处理软件对试验结果进行计算分析。[结果]从而得出涂层体系中各等效元件的参数来评估涂层的性能,并制定涂层老化失效电化学评定标准。[结论]盐雾老化和紫外老化涂层性能实验结果表明,基于交流阻抗技术及相应的电化学评价参数能够快速准确地对涂层性能进行综合评价。
[Objectives]Coating on the surface of ships is a common method of ship anti-corrosion.The corrosion resistance of the coating directly reflects the corrosion degree of the ship's surface.Although coating has been used as an effective anti-corrosion technology on ships for decades,there has been a lack of rapid and effective test methods for the corrosion resistance of the coating.[Methods]In this paper,a reasonable equivalent circuit model of the coating system was established,and the salt-fog aging and UV aging coating performance experiments were carried out on the test coating by AC impedance testing technology.The Matlab data processing software was used to calculate and analyze the experimental results.[Results]The parameters of each equivalent component in the coating system were obtained to evaluate the performance of the coating,and the electrochemical evaluation criteria for coating aging failure were established.[Conclusions]The results of salt-fog aging and UV aging coating performance experiments show that the performance of the coating can be comprehensively evaluated quickly and accurately based on the AC impedance technique and the corresponding electrochemical evaluation parameters.
