ntrs.nasa.govZinc is also a common type of plating. The hot-dip method of zinc plating is known commercially as galvanizing. Zinc can also be electrodeposited. Because zinc plating has a dull finish, it is less pleasing in appearance than cadmium. However, zinc is a sacrificial material. It will migrate to uncoated areas that have had their plating ...

ZINC ELECTROPLATING Zinc Electroplating - Pavco
www.pavco.comthe zinc plating systems. ALKALINE NON-CYANIDE ZINC In early cyanide-free alkaline zinc plating systems, cyanide was replaced by complexing or chelating agents such as sodium glucon - ate, triethanolamine, or polymeric amines. The resulting baths presented problems with both waste treatment and co-deposition of iron.
