Cadmium Plating Alternatives and Coating Process ...

Zinc-Iron: This alloy is an excellent cadmium plating alternative, with the ability to deposit very evenly and at high thicknesses. In addition to being a relatively cheap option, zinc-iron offers excellent corrosion resistance compared to other options. The primary downside to this particular material, however, is the lack of lubricity, especially when compared to tin-zinc. The system used to ...

Why Zinc Nickel Alloy Plating Is Replacing Cadmium Zinc ...

In 1956, over 60 percent of all cadmium was used for coating iron or steel. However, over the years, this has decreased to as little as 7 percent in 2006, and materials like zinc nickel plating are seeing more and more use. In Search of Alternatives. When the industry was looking for a viable replacement to cadmium, they tried zinc electroplate ...

Alternatives to cadmium in aerospace Engineer Live

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. With many other suggested cadmium alternatives, it is necessary for OEMs and MRO professionals to also adopt new processes and procedures,

Long-Term Performance of Cadmium Alternatives

Much of their corrosion resistance capability was established on pristine surfaces in NSS with an unspecified plating thickness. The high nickel (10-14%), zinc-nickel alloys and tin-zinc were reported to give superior performance.
