A material (20) is coated to enhance and add desirable properties through a metalliding process employing an atmosphere (14) substantially free of oxygen and an electrolytic bath (18) within the atmosphere (14). An electrically conductive substrate (20) to be coated is submerged within the bath (18) as a cathode (20) along with multiple anodes (26), each anode (26a, 26b, 26c) having a distinctive composition from the other. A variable power source (30) provides distinctly selected current densities to each of the anodes (26) so as to result in a coating of the substrate (20) by each anode material (26a, 26b, 26c) in proportion to the applied current densities. |
