The material (20) is coated by a metalliding method using an atmosphere (14) substantially free of oxygen and an electrolytic bath (18) in the atmosphere (14) to enhance and add desired properties. . The conductive substrate (20) to be coated is immersed in the bath (18) as a cathode (20) together with a plurality of anodes (26a, 26b, 26c) having different compositions. A variable power source (30) supplies a separately selected current density to each anode (26), with each anode material (26a, 26b, 26c) in proportion to the applied current density said substrate (20).
