技术背景
Steelcorrosionmakebiglossintheworld,the20%-40%oftheannualoutputofsteelarerottedallovertheworld（about1000millionton）.Thelosscausedbycorrosioninindustrialdevelopedcountriesoccupied2%-4%oftheirGDP.InAddition,shutdownandaccidentscausedbycorrosionthenlosswillbemorestartling.
金属腐蚀给全球带来严重损失，全世界每年金属总产量的20%-40%的被腐蚀损耗。
工业发达国家每年因为金属腐蚀造成的经济损失占国发生产总值的2%-4%，如果再加上因腐蚀而造成的停工和事故等间接损失，数字将会更加惊人。
Thetraditionalanti-corrosiontechnologyiswithsomelimitations
传统的防腐技术存在诸多缺陷

采用锌材料阴极防护的方式，作为一种有效的钢铁防护手段，已经得到越来越多的应用，诸如热浸镀锌、电镀锌、电弧喷锌、热喷锌等工艺手段，但鉴于这些工艺存在施工难度大、环境污染重、能耗高、锌层受损难修复等弊端，使得发展受限。
