Definitions

  • This invention relates to the electrodeposition of tin-nickel alloy.
  • the electrodeposition of tin and nickel separately is well known as is also the principle of using small quantities of a second metallic ion to improve the smoothness of the deposit of the primary metal.
  • a nickel salt to improve the tin coating deposited from a bath containing stannous chloride and alkali fluoride but to obtain satisfactory deposits from this bath it is essential that it contains one or more of the organic addition agents used in the electro-plating industry for improving the smoothness of deposits.
  • I electrodeposit tin-nickel alloy coatings containing not more than 90% nor less than 50% of tin from an aqueous solution of appropriate salts of tin and nickel containing the respective. metals in proportions between 2:1 and 1:7.
  • the electrolyte must contain tin and nickel cations and may contain the cations of an alkali metal including ammonium.
  • the anions may be chlorides alone, or chlorides and fluorides, or chlorides sulphates and fluorides, or fluorides alone.
  • baths used in accordance with the present invention are that they produce satisfactory smooth deposits in the absence of organic addition agents.
  • the tin and nickel cations may be replenished by using anodes of an appropriate tin-nickel alloy.
  • anodes of an appropriate tin-nickel alloy may be used.
  • separate tin anodes and nickel anodes may be used.
  • replenishment may be effected either by passing the total current through each anode successively for an appropriate time or by using the tin and nickel anodes simultaneously and apportioning the current through them appropriately.
  • Example II G./l. SnClz, 2H2O 100 NiF2 75 16 NiCl2, fiHzO 325 K01 100 Temperature 65 C., 20 amps/sq. ft. Coating Sn 20
  • Example III G./l. SnF2 NaF '75 25 NiC12, 6H2O 200 Temperature 65 C., 27 amps/sq. ft. Coating Sn Example IV
