Definitions
- the invention relates to a galvanic bath for the deposition of nickel-molybdenum alloys on a surface of an object.
- nickel-molybdenum alloys for example, contact elements of connectors can be coated.
- further layers for example composed of silver / silver alloys or gold / gold alloys or copper / copper alloys, can be applied.
- Galvanic baths based on ammonium-nickel and ammonium-molybdenum complexes are generally classified by the experts as less stable.
- insoluble molybdenum compounds are formed, for example MoO (OH) 3
- Galvanic baths for the deposition of a nickel-molybdenum alloy for the deposition of a nickel-molybdenum alloy.
- the galvanic baths also contain ammonium and / or
- the object of the present invention is to provide a stable alloying bath which enables deposition of the nickel-molybdenum alloys having a high molybdenum content.
- the object is achieved by a galvanic bath according to claim 1.
- the galvanic bath according to the invention can be produced in a simple manner. It is also environmentally friendly.
- a galvanic bath may consist of an aqueous, preferably
- Ammonium complexes each of nickel and / or molybdenum
- citric acid and / or the citrate can also their citric acid and / or their citrate
- the bath contains, for example, ketoglutaric acid and / or aconitic acid and / or ⁇ -ketoglutarate and / or Ketoglutarate and / or aconitate.
- ketoglutaric acid and / or aconitic acid and / or ⁇ -ketoglutarate and / or Ketoglutarate and / or aconitate preferably, the
- aforementioned substances a concentration between 0, 1 and 0.6 mol / L, more preferably between 0, 1 and 0.4 mol / L in the bath.
- Oxidation levels in the galvanic bath is present.
- the soluble complex compounds of molybdenum can be prepared prior to their use according to the invention in that, for example, molybdenum salts in which the molybdenum in
- the molybdenum in different oxidation states is produced by a chemical and / or electrochemical reduction of the molybdate ions. After reduction, molybdenum ions are in the
- Salts of nickel and / or cobalt and / or iron and / or phosphorus and / or rhenium and / or palladium and / or platinum, which in combination with molybdenum salts permit different alloy compositions of the layer, are advantageously used as the electrolyte. So you can to 50% -Gew. Separate molybdenum.
