Definitions
- the invention relates to an electroplating bath for applying zinc-nickel coatings with an anode, a cathode and an alkaline electrolyte.
- the alkaline zinc-nickel electroplating baths disclosed in German patent specification 37 12 511 have recently been used, which have the following composition, for example: 11.3 g / l ZnO 4.1 g / l NiSO 4 * 6H 2 O 120 g / l NaOH 5.1 g / l polyethyleneimine.
- the amines contained in the electroplating bath serve as complexing agents for the nickel ions, which are otherwise insoluble in the alkaline medium.
- the composition of the baths varies depending on the manufacturer.
- the electroplating baths are usually operated with insoluble nickel anodes.
- the zinc concentration is determined by adding zinc and the nickel concentration by adding a nickel solution, for example a nickel sulfate solution, kept constant.
- the formation of the second phase is due to a reaction of the amines, that in alkaline solution on nickel anodes to nitriles (among others can also be converted to cyanide). Due to the decomposition of the amines new complexing agents must also be continuously added to the bath, which drives up the cost of the process.
- Anodes other than nickel anodes cannot be used because of this dissolve in the alkaline electrolyte, which is also disadvantageous Effects on the quality of the coating.
- the problem underlying the invention is an alkaline one To create zinc-nickel electroplating bath, which is inexpensive zinc-nickel coatings delivers high quality.
- the invention proposes the anode of the to separate alkaline electrolyte through an ion exchange membrane.
- a cation exchange membrane has proven to be particularly advantageous made out of a perfluorinated polymer, since this has negligible electrical resistance, however have a high chemical and mechanical resistance.
- the zinc-nickel bath acts as a catholyte in the solution according to the invention.
- sulfuric or phosphoric acid can be used as the anolyte become.
- the anode material used in the electroplating cell according to the invention usual anodes, e.g. Platinized titanium anodes are eligible because of this are no longer exposed to the basic zinc-nickel bath.
- the 1 shows an electroplating cell 1, which has an anode 2 and a cathode 3, which is the workpiece to be coated.
- the the Catholyte 4 surrounding the cathode is alkaline and consists of a zinc-nickel electroplating bath known composition, in which as a complexing agent for Nickel ion amines are used.
- the anolyte 5 surrounding the anode 2 can consist for example of sulfuric or phosphoric acid.
- Anolyte 5 and catholyte 4 are separated from one another by a perfluorinated cation exchange membrane 6 Cut. This membrane 6 enables an unimpeded flow of current through the Bad, however, prevents the catholyte 4, especially those contained therein Amines, comes into contact with the anode 2, which results in the introduction to the description detailed reactions including their adverse effects be avoided.
