1,197,126. Electrodeposition of nickel coatings. CLEVITE CORP. May 20, 1968 [Dec. 11, 1967], Addition to 1, 137, 960. No. 24009/68 Heading C7B. A metal composite as described in the Parent Specification which is produced by electrocathodic deposition of a nickeliferous coating which is not sound or smooth plate from an aqueous solution containing 3‹5-25 gm/1 Ni derived from a water soluble nickel salt, from 20gm/l to the limit of solubility of ammonium ion, having a pH of 1-9 and a temperature of from just above freezing point of the solution to 30‹ C, using a current density of 50-300 amps/sq.ft. for 0À2-3 mins., but excluding metal composite as produced by the method claimed in the Parent Specification. Other details are as described in the abridgment of the Parent Specification. Nickel formate may also be used herein as the source of nickel ions. The metal composite thus formed may be used in production of printed circuits. |
