Electrochemically, alloys can be designed to produce different corrosion
characteristics than their alloying elements. It is possible, therefore, to
maintain the sacrificial protection of zinc coating over steel, but at a
different corrosion rate. As a result, the alloy corrodes at a much slower rate
than zinc alone, affording better corrosion protection. Some of these alloys
have been found to be excellent replacements for cadmium plating in many
applications.
