材料保护 :电化学保护 通过改变极性或移动金属的阳极极化电位达到钝态区来抑制或降低金属结构腐蚀的材料保护技术。从伽法尼电池的两个金属电极来观察﹐腐蚀总是发生在阳极上。阴极保护就是在潮湿的土壤或含有电解质(如盐等)的水液等电解液中﹐利用牺牲阳极(如锌﹑铝等)或外加电流的惰性阳极﹐使被保护的钢铁结构成为这种人为的伽法尼电池中的阴极。在同一腐蚀环境中﹐活性较大的是阳极﹐较小的是阴极﹐例如在海水中﹐锌与低碳钢间如构成电解电池﹐锌就是阳极﹐钢就是阴极﹔但如果钢与不锈钢形成电解电池时﹐钢又变为阳极﹐不锈钢是阴极。所谓阴极﹐实际上是使电解液中的阳离子获得电子而还原的一个电极。因此﹐利用外加直流电源使它获得电子补充﹐也属於阴极保护方法。在不同的腐蚀介质中所需的保护电流密度不一。钢在土壤内﹐约为 0.0001～0.005安/分米3﹐在流动海水中约为0.0003～0.0015安/分米3﹐而在流动淡水中为0.005安/分米3 。阴极保护广泛用於保护地下管道﹑通信或电力电缆﹑闸门﹑船舶和海上平台等以及与土壤或海水等接触面积很大的工件﹐电化学保护与涂装结合则更为经济。城市和大型工厂的地下金属设备可採用这种保护方法﹐但需要注意杂散电流不致影响邻近地下金属设施的加速腐蚀。阳极保护主要用於保护钢﹑不锈钢和鈦等在浓硫酸和磷酸等强介质中的腐蚀。活性-钝性金属在阳极极化时﹐即电流导入而產生电位变化时﹐其极化曲线中有显著的活化﹑钝化和过钝化区(见图 阳极保护原理的极化曲线 )﹐对於这种情况﹐可利用稳压电源将电位控制在钝化区间﹐使腐蚀电流值降到最低限度。
