As a proven cadmium plating replacement, zinc-nickel plating (ZnNi) offers excellent sacrificial corrosion protection for steel and very good protection against white rust formation. The coating's high hardness combined with low hydrogen embrittlement makes it a viable replacement solution.
Jul 01, 2008· However, cadmium is a heavy metal, and the cyanide bath commonly used to produce cadmium deposits is highly toxic. For these reasons, The European Union End of Life Vehicle Directive (ELV) banned the use of cadmium and other heavy metals in the automotive industry in fall 2000, and additional environmental initiatives in Europe and the U.S

Traditional coatings such as pure zinc will set up a galvanic cell when adjacent to aluminium. This will speed up corrosion which is not desirable on an aircraft component! Over the last few years the aerospace industry has started to specify zinc nickel alloy as a replacement for cadmium.
The coating is normally specified in thickness' between 5 and 25 µm depending on the severity of the atmosphere. Chromate post-treatment of the coating can increase coating life. (a) Electroplating. Cadmium is electrodeposited on the metal article from an electrolyte solution of cadmium
Perhaps the biggest advantage of adopting zinc-nickel as an alternative to cadmium, aside from its performance benefits, is the fact that it is a drop-in replacement process. The technology already used for cadmium plating needs not change.

Cadmium plating is used for two primary purposes: 1. To provide sacrificial corrosion protection to steel components. 2. To provide galvanic compatibility between electronegative materials such as Al and Mg, and more noble materials such as stainless steels. Cd plate is normally chromated with a typical hexavalent chromium conversion coating.
