摘要:

为研究锌粉形态对溶剂型富锌涂层阴极保护性能及机理的影响，制备了片锌取代比分别为0%、20%、100%的涂层样品。采用3.5%NaCl溶液浸泡开路电位(OCP)监测、盐雾试验和电化学阻抗谱(EIS)进行分析。结果表明：20%片锌取代比的涂层阴极保护效果最佳，其阴极保护时间显著提升。片状锌粉的加入可增强涂层的屏蔽性能，提高锌粉搭接率，增加涂层内有效电连接数量，从而延长阴极保护时间。

关键词 ：富锌涂层, 阴极保护, 涂层失效

Abstract：

To investigate the effect of the shape of zinc powder on the cathodic protection performance and mechanism of solvent-based zinc-rich coatings, three acrylic hybrid resin based coatings with zinc powder pigments composed of mixture of spherical zinc with 0%, 20%, and 100% flake zinc, namely replacing partially the spherical zinc of the pigment with the flake zinc, were prepared on Q235 carbon steel plate respectively. Then the corrosion performance of the Q235 steel with coatings was assessed via immersion test in 3.5%NaCl solution with open circuit potential (OCP) measurement and electrochemical impedance spectroscopy (EIS), as well as salt spray test. The results show that among others, the coating with pigment of spherical zinc and 20% flake zinc exhibits the best cathodic protection performance, i.e. the coating may provide significantly enhanced cathodic protectiveness for the steel substrate. It is concluded that the incorporation of flaky zinc powder can enhance the barrier properties of the coating, increase the zinc powder contact efficiency, and augment the number of effective electrical connections within the coating, thus extending its life-time of cathodic protection.

Key words： zinc-rich coatings cathodic protection coating failure
