工业界一直在寻找更好的方法和材料来防锈。镉和锌已经使用了几十年。现在，国际社会正在寻找这两种金属的替代品。锌合金已在多个大洲成功地用于汽车工业的电镀零件。锌与镍、锡、铁或钴形成合金，具有优异的防腐性能。将讨论它们的个人特征。此外，还将对常规锌表面铬酸盐转化涂层的适当固化进行回顾。

Industry is always looking for better methods and materials to prevent rust. Cadmium and zinc have been used for decades. Now the international community is looking for alternatives for both metals. Zinc alloys have been successfully used to electroplate parts for the automotive industry on several continents. Zinc alloyed with nickel, tin, iron, or cobalt give superior corrosion protection. Their individual characteristics will be discussed. Also, ideas for the proper curing of chromate conversion coatings on conventional zinc will be reviewed.
