Abstract

856,405. Platinum electro-plates. SEL-REX CORPORATION. June 26, 1959 [Aug. 6, 1958], No. 22070/59. Drawings to Specification. Class 41 An electrolyte for depositing relatively thick platinum coatings electrolytically consists of platinum diamino-dinitrite dissolved in an aqueous solution of sulphamic acid and then diluted to contain at least 6g. of the metal per litre of solution. Plating conditions specified are 65‹ to 100‹C., 20 to 100 A.S.F. at 1 to 3 volts, and preferably the electrolyte is agitated. Reference is made to making platinum shells by electro-forming, and to plating graphite with platinum with a nickel top coat. U.S.A. Specification 1,779,436 is referred to.
