ABSTRACT:
A method for providing an electroless plate, particularly a discontinuous plate for uses such as for electrolytic cell cathodes. A nickel substrate is interdiffused with a second metal which, when leached out leaves a hydrogen adsorbing surface upon the substrate. The substrate is then contacted with a dilute, at least 20 ppm, solution of the plating metal, preferably with the plating metal in anionic complex in the solution. Following immersion, the resulting plated substrate is passed through a reducing flame.
