Research and testing has shown that zinc alloys in particular are excellent alternatives to cadmium for plating. All zinc alloys are relatively corrosion resistant and can handle up to 370 inch-lbs of torque, making them relatively wear-resistant. Further qualities, including plating methods, depend on the specific zinc alloy.

PVD is a desirable alternative to electroplating and possibly some painting applications because it generates less hazardous waste and uses less hazardous materials (i.e., no plating baths). PVD processes as a substitute for chromium plating in decorative applications represents a development toward an environmentally clean technology.

Cadmium Plating Alternatives and Coating Process ...

Before the 1960s, cadmium, also referred to by its elemental abbreviation "Cd," was the go-to material for numerous industries. The blossoming aerospace industry and rapidly expanding military industry both sought cadmium for use in several key mechanical applications, but things changed when expanding research discovered several drawbacks of the material, both 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.


Cadmium Plating Alternatives | PCI Magazine

Two alternative cadmium plating baths - one based on sulfuric acid and the other a neutral-pH formulation - offer a less toxic alternative to traditional cyanide baths. Acid cadmium plating baths are currently in large-scale industrial use. The electrolyte is composed of 3 to 5% sulfuric acid and 3 to 6 oz/gal of cadmium.


Cadmium Plating Alternatives - SERDP-ESTCP

Cadmium plating is used for two primary purposes: 1. To provide sacial 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.


Replacement for Cadmium Plating for Aircraft Landing Gear

Replacement of cadmium plating in aircraft landing gear manufacturing and maintenance is a high priority for the Department of Defense (DoD). Military aircraft maintenance depots use cadmium plating extensively to apply corrosion resistant coatings to various high-strength steel aircraft components during manufacture, repair, and overhaul.
