This type of cadmium plating has a phosphate supplementary colorization and is usually employed as a paint base. Cadmium plating classifications are divided into 1, 2, and 3, based on the thickness of the coating. For example, class 1 is a coating of 0.0005 in., class 2 is 0.0003 in., and class 3 is rated at 0.0002 in. Cadmium Plating Expertise

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.
