· Cadmium plating is usually done by electroplating, in which an electric current is used to deposit cadmium onto the metal surface. The cadmium ions in the solution are attracted to the negatively charged metal surface, where they replace some of the atoms in the surface layer.

· Cadmium plating, when vital for critical components where substitute plating would render them dangerous, must only be done in a proper industrial facility. Again, hopefully you're working with an imitation, not actual cadmium -- in which case, ask the hobby supplier for guidance because we don't even know what metal or alloy it is.
