Bright and smooth functional chromium is deposited using a plating bath containing chromic acid, 40-150 g/l sulfoacetic acid, an iodine-releasing agent e.g. - iodate, and a nitrogen organic compound e.g. glycine as a depolariser. The bath is otherwise free of carboxylic acids, fluoride, bromide and selenium ions. The process can be operated at conventional plating current densities e.g. 1-10 asi:. |
