Definitions

  • the object of the present invention is a process for'direct nickel-plating of aluminum and its alloys, including those aluminum alloys which contain a high proportion of magnesium.
  • the object of the present invention is a direct nickel-plating process for aluminum and its alloys which can overcome the above mentioned disadvantages.
  • sulphates I use for instance a sulphate of a heavy metal, such as manganese, zinc, cadmium. The said sulphate will be used in proportions by weight which are substantially equal to the alkaline cyanide contained in the bath.
  • the piece After being degreased, the piece is rinsed in running water and then passed through the nickel-plating bath.
  • the said bath is a bath of polyaminonickelo-sulphate, i. e. of a form such as NiSOANI-ma in which one or more of the (NHa) groups may be replaced by the corresponding number of (H), such as for instance the:
  • I preferably add ammonium acetate to the bath to maintain thestability of the said nickel compounds, and add a magnesium salt (e. g. sulphate or chloride, for increasing the conductivity of the bath and for increasing the malleabllity of the deposited nickel.
  • a magnesium salt e. g. sulphate or chloride
  • the said bath may be cold or hot operated under 2 to 4 volts and .25 to 6 amperes per square decimeter.
  • V degreasing bath also contains an organic colloid
  • treatment is eiiected under a voltage-which volts.
  • a process oi! nickel-plating aluminum objects and aluminum alloy objects which comprises first electrolytically degreasing said objects in a bath containing several per cent or a cyanide,
  • the nickel-plating bath comprises a polyaminonickelo-sulphate and a substance selected from the group consisting of ammonium acetateand magnesium sulphate.
  • a process of nickel-plating a metallic object which contains metallic alumium asa major com. ponent which comprises first degreasing said object while it constitutes the cathode in an electrolyte which contains several per cent of an alkali and several per cent of cyanide and several per cent of zinc sulphate, and thereafter electroplating nickel thereupon while said object constitutes the cathode in an electrolyte which is an aqueous solution of polyamino-nlckelo-sulphate, ammonium acetate and um sulphate.
