在水中或潮湿土壤中工作的金属构件表面防止锈蚀的最有效的工艺方法之一是电化阴极防蚀法。在航海造船业中,在修建地下管道时早已广泛采用电化保护方法。最近10～15年,全苏水工科学研究院和莫斯科水工钢结构专业设计局同时开始采用电化保护用
One of the most effective processes to prevent rust on the surface of metal components that work in water or in moist soil is the electrochemical cathodic protection. In the marine shipbuilding industry, the electrochemical protection method has long been widely used in the construction of underground pipelines. In the recent 10 ~ 15 years, Quanzhou Institute of Hydraulic Engineering and Moscow Steel Structure Design Bureau at the same time began to use electrochemical protection
