Definitions

  • the invention relates to a method for the adhesive metallization of titanium or titanium alloys by electroless deposition of a nickel-phosphorus alloy with subsequent heat treatment to form nickel-titanium diffusion layers.
  • the galvanizing of the materials mentioned is difficult because the surface is covered with a passivation layer.
  • the passivation layer In order to metallize titanium or titanium alloys firmly, the passivation layer must be removed. This is done in a known manner using aqueous solutions of hydrofluoric acid or fluoride-containing acids. If the passivation layer is removed from the surface, titanium or titanium alloys can be electroplated.
  • the object of the present invention is to provide a method of the type described in the introduction with which adherent nickel layers on titanium or titanium alloys can be produced without roughening the surface beforehand.
  • the roughening of the surface is avoided in the treatment step, which not only leads to a more homogeneous surface structure, but also ensures easier handling overall. Furthermore, it is independent of the method according to the invention whether the heat treatment takes place after the deposition of the nickel-phosphorus alloy without external current or only after the final decorative or functional coating.
  • the electroless plating of the nickel-phosphorus invention takes place in a manner known per se using conventional chemical nickel baths.
