Definitions

  • the invention relates to a method for producing tin-graphite or tin-lead-graphite layers, in which at least the tin layer is electrodeposited.
  • the invention also relates to a bath for the galvanic deposition of such dispersion coatings from an aqueous solution of tin (II) and optionally lead (II) salts.
  • Tin layers can be applied by hot-dip tinning or also by means of galvanic baths. From DE-OS 24 13 402 slidable tin layers for electrical sliding contacts on plug-in elements are known, in which the tin or lead layers, in particular galvanically applied, in the ball polishing process with the addition of substances conducive to sliding, such as graphite powder, in the border area the surface is incorporated and solidified at the same time cold.
  • the graphite is therefore only mechanically incorporated into the interface to a depth of about 0.5 ⁇ m, for which a separate operation is required.
  • the shape of the parts to be treated is important, with an optimal distribution over all Interfaces of the contact cannot be reached.
  • the object of the invention is to provide an improved method for applying layers to tin-graphite or. Tin / lead-graphite base and the associated agents.
  • the object is achieved in that the tin-graphite or tin / lead-graphite layer is galvanically produced as a dispersion coating in a single operation, with a plating bath on a strongly acidic basis in which graphite powder is dispersed by means of an acid-resistant wetting agent , and working at temperatures ⁇ 35 ° G.
  • the tin-graphite coating is advantageously electroplated at current densities of 1 to 15 A / dm 2 .
  • a bath for the electrodeposition of tin-graphite dispersion coatings from an aqueous solution of tin-II and optionally lead-II salts is used in which the solution has a pH ⁇ 2 and contains an acid-resistant wetting agent
  • the wetting agent is advantageously an organic substance which has little or no tendency to foam.
  • Such wetting agents can be one or more of the substances from the group consisting of phenol and dibutylaniline, gelatin and cresol, cresol sulfonic acid and 2-methylpentyl sulfate, dibutyl sodium naphthalene sulfonate or sodium lauryl sulfate and be sodium xantogenate.
  • the graphite powder dispersed in the wetting agent preferably has a grain size distribution ⁇ 1 to 5 ⁇ m, i.e. 70% of the graphite particles are smaller than 1 ⁇ .
  • suitable wetting agents were found which are able to disperse the fine graphite grains and at the same time to incorporate them into the galvanically deposited tin or. Adequate guarantees of tin / lead layers.
  • the galvanic baths mixed with the specified wetting agents are preferably used at room temperature or at temperatures ⁇ 35 ° C
  • the invention allows galvanically deposited tin and tin / lead layers, which can also have a low antimony content, which increases the hardness of the coating to considerably improve the abrasion resistance.
  • the necessary plug-in force is reduced in spite of high contact pressure. It could be demonstrated in detail that the galvanically produced dispersion coatings made of tin-graphite or. Tin / Bfei graphite the abrasion resistance by 10 to 25 times compared to the previously known tin or. Tin / lead layers is increased
  • the deposited tin layer contained 1.6% by weight of graphite.
  • the abrasion resistance increased 10 times.
  • the deposited layer contained 2% by weight of graphite.
  • the abrasion resistance increased 18 times.
  • the deposited tin layer contained 1.8% by weight of C.
  • the abrasion resistance compared to a pure tin layer was increased twice.
  • the deposited tin / lead layer (90/10) contained 1.8% by weight of graphite and 1% by weight of antimony.
  • the abrasion resistance compared to pure tin / lead layers has been increased 25 times
  • the deposited tin / lead layer (60/40) contained 1% by weight of graphite and 1% by weight of antimony.
  • the abrasion resistance increases 10 times compared to a pure tin-lead layer
