Abstract:
The method for electroplating a layer of conformable nickel on a metal substrate comprising placing a metal substrate made of a material selected from the group consisting of copper, copper alloys, and nickel alloys in a nickel bath consisting essentially of about 75 g/l to about 130 g/l of nickel as a nickel complex, about 3 g/l of a nickel salt, about 30 g/l to about 45 g/l of a buffer, and about 5 m/l to about 20 m/l of a fluorochemical wetting agent and maintaining the pH of the bath in the range of about 2 to about 2.5 while applying a current density of about 5 Amps/dm.sup.2 to about 50 Amps/dm.sup.2 for a period of time sufficient to plate a layer of nickel of the desired thickness onto the substrate.
