Anode configuration for nickel-phosphorus electroplating |
摘要 |
An anode configuration is provided particularly for a bath that is used for electrolytically plating a substrate with a nickel and/or cobalt phosphorus alloy. The anode comprises a plurality of widely spaced portions of material, preferably of platinum or rhodium. The anode configuration is such that the anode has a very high current density in use-at least 200 amperes per square foot and preferably 500 amperes per square foot. The wide spacing of the anode portions may be provided in a number of different ways. A platinum wire may extend between titanium screws attached to a pair of parallel spaced titanium buses, in a zig-zag manner. A platinum wire may be welded at its opposite ends to a titanium bus, and helically wrapped around the bus, with the welding junctions covered by an insulating material (e.g. vinyl). A platinum tube may be shrink fit onto a titanium bus.
