THE LARGEST USE of zinc is as a protective coating for steel, and therefore corrosion tests and data [1,2], have been developed and widely used to describe its performance in specific situations or determine its usefulness for new applications. The corrosion resistance of zinc in cast or wrought form is less often a criterion for selection for a given application, although substantial published corrosion data on these product forms exist . Another class of product, zinc anodes, is used to provide corrosion protection to iron and steel structures that are buried or immersed by simply making an electrical connection between the ferrous material and the anode. By this means, it is not necessary to provide a protective coating to the ferrous object. The use of a coating, however, reduces the current demand and extends anode life. Corrosion data for this application are also widely published .
