热镀锌钢表面硅烷/硅酸盐复合膜的耐蚀性能研究 吴海江1,卢锦堂2 (1.湖南科技大学,先进材料制备与应用技术研究所,湖南,湘潭,411201;2.华南理工大学,材料科学与工程学院,广东,广州,510641) 摘要:为了改善硅烷膜的耐蚀性,将硅烷化热镀锌钢板用硅酸钠溶液封闭后处理,获得了硅烷/硅酸盐复合膜.采用中性盐雾试验(NSS),湿热试验,盐水全浸试验和电化学交流阻抗谱(EIS)评价了膜层的耐蚀性能.结果表明,与单一硅烷膜相比,复合膜的耐蚀性能明显提高,超过了常规铬酸盐钝化膜.尤其是在5%NaCl溶液中,复合膜的低频阻抗数值随浸泡时间的增加先增大后减小,表明其具有一定的"自修复"能力. 关键词:热镀锌钢; 复合膜; 硅烷膜; 硅酸钠; 耐蚀性; hot-dip galvanized steel; composite films; silane film; sodium......
