Evaluation of Aluminum-Manganese as a Cadmium Replacement
Abstract
Aluminum-manganese is currently being evaluated as a replacement for cadmium plating. Aluminum-manganese is applied by electroplating in molten salt and as such the process can plate internal diameters, complex geometries, and threaded applications. The salt bath is operated at 190 degrees Celsius and is compounded of aluminum chloride, sodium chloride, potassium chloride, and a small amount of manganese chloride. Aluminum-manganese has potential for use in high strength steel applications where other electroplated cadmium alternatives such as tin-zinc and zinc-nickel have concerns with environmentally assisted cracking. Aluminum-manganese should prove to be much more affordable than ion vapor deposition and physical vapor deposition processes.
