Definitions

  • the present invention relates to an aqueous solution for Deposition of tin-zinc alloys and especially one Electroplating bath which is used to deposit tin-zinc alloys from a cyanide-free tin (II) -zinc (II) solution with simple bath guidance.
  • Products made by electroplating with a tin-zinc alloy are characterized by a excellent corrosion resistance. Especially the Resistance to hydraulic fluid and aqueous Salt solutions leave such coated products for Automotive industry seem interesting. Also in the Broadcasting, electrical and construction industries are made with tin-zinc alloys coated products due to their Corrosion resistance and their excellent solderability used.
  • the electroplating baths usual up to now contained tin in the + IV oxidation state and cyanide ions.
  • electroplating baths have the disadvantage that for Deposition of tin (IV) ions requires more energy is required as for the separation of tin (II) ions.
  • the bath tour includes the difficulty that the dissolution of the anode, which advantageously also consists of a tin-zinc alloy is formed by forming a film the formation of tin (IV) ions is promoted by means of polarization must become.
  • the thickness and composition of the deposited tin-zinc alloy on the current density and thus dependent on the geometry of the substrate.
  • the Toxicity of the cyanide ions makes industrial use difficult.
  • the object of the present invention is therefore Providing an electroplating bath solution for Deposition of tin-zinc alloys that are not cyanide contains, by the deposition of tin from a tin (II) ions containing solution with a low energy consumption the separation, and their bath management over wide Ranges of the freely selectable parameters is not critical and flawless and discolouration-free deposits.
  • aqueous solution which, in addition to tin (II) and zinc (II) ions, are aliphatic Carboxylic acids and / or their alkali salts as complexing agents, and a mixture of anionic and non-ionogenic Contains surfactants as grain refiners.
  • the aqueous solution according to the invention furthermore contains aromatic aldehydes and / or aromatic ketones as brighteners.
  • a special, advantageous compound of formula (II) is o-Cl-benzaldehyde.
  • the pH of the solution is preferably 2-8, particularly preferred at 3-5.
  • tin (II) and zinc (II) ions are preferred in the form of Chlorides, sulfates or alkyl sulfonates used.
  • one or more conductive salts of the corresponding anions are additionally used. NH 4 Cl and / or NH 4 (CH 3 SO 3 ) are preferred.
  • Preferred aliphatic carboxylic acids in the invention aqueous solution are hydrocarboxylic acids and aminocarboxylic acids and particularly preferred is citric acid or its Alkali metal salts.
  • Aliphatic or aromatic sulfonates are preferably used as anionic surfactants.
  • the electroplating bath for the deposition of zinc-tin alloys can also contain aromatic and / or heterocyclic carboxylic acids or their alkali salts according to formula (XIV) contain.
  • carboxylic acids are Nicotinic acid and / or Na benzoate.
  • the concentrations of the individual components are advantageously chosen within the following ranges: Zinc (II) ions 5 g / l to 50 g / l particularly preferred 20 g / l to 25 g / l Tin (II) ions 0.5 g / l to 5 g / l particularly preferred 1 g / l to 3 g / l aliphatic carboxylic acids 30 g / l to 200 g / l particularly preferred 60 g / l to 140 g / l non-ionic surfactants - according to formula (III) 0 g / l to 10 g / l particularly preferred 0 g / l to 2 g / l - according to formula (IV) or (V) 0 g / l to 10 g / l particularly preferred 0 g / l to 2 g / l anionic surfactants 5 g / l to 30 g / l particularly preferred
  • the present invention also includes the use of the above described aqueous solution for the deposition of tin-zinc coatings, especially tin-zinc coatings with a Zinc content from 10 to 50% by weight.
  • the invention is based on the following Embodiment explained in more detail.
  • An aqueous solution was prepared from the following components:
