Ni-P-W multilayered alloy coatings produced by pulse plating

The possibility of producing multilayered alloy coatings consisting of alternate amorphous layers, by the electrodeposition method, using pulsed current was investigated. The alternate metallic amorphous layers were selected to consist of Ni-P-W ternary alloys, in order to study the effect of the incorporation of a third element in the structure of an electrodeposited Ni-P multilayered alloy coating. The well-defined layered structure found in the Ni-P-W multilayered alloy coatings, consisting of X-ray amorphous layers, shows that production of a ternary Ni-P-W multilayered alloy coating with the selected method is feasible and this may expand the potential applications of a Ni-P based multilayered alloy coating.
