我国沿海地区水工、港工钢结构长期浸在淡水及淡海水介质中,受到不同程度的电化学腐蚀,采用牺牲阳极法进行保护是一种较好的简易方法。江苏省水科所材料结构室和四港管理处新洋港闸管所在有关单位的协助下,近几年来进行了高硅铁合金阳极研制、铝基多元合金牺牲阳极筛选及在淡水、淡海水水工闸门上应用的研究,并于一九八四年十二月通过技术鉴定。
China’s coastal areas hydraulic engineering, long-term industrial steel structure immersed in freshwater and light seawater medium, by varying degrees of electrochemical corrosion, the use of sacrificial anode method is a better and easier method. In recent years, with the assistance of the relevant units of the Materials Management Office of Jiangsu Province Water Branch and the Xin Yang Gang Control Office of the Si Hong Kong Management Office, the research and development of high-silicon iron alloy anodes, aluminum-based multi-alloy sacrificial anode screening, Application of the gate of the study, and in December 1984 passed the technical appraisal.
