Definitions

  • Phosphating processes have been used for decades to protect against corrosion, to increase the adhesion of subsequent coatings, such as e.g. a lacquer layer and / or to improve the Kaltumform s in use.
  • aqueous zinc-rich phosphating solutions are used for this purpose.
  • bodies are pretreated with very high quality zinc manganese nickel phosphating, which provide a very high corrosion protection and a very high paint adhesion before the paint system is applied.
  • Lubricant carrier salts calcium hydroxide or phosphates, in particular based on zinc phosphate, can be applied as a first layer to the surfaces of the metallic workpieces to be formed.
  • these coatings additionally require a lubricant layer so that the workpieces coated in this way can be used for cold forming.
  • the content of an alkaline earth metal-containing phosphating solution of fluoride and complex fluoride is preferably zero, since these contents often lead to precipitation.
  • the content of an alkaline earth metal-free phosphating solution of fluoride or / and complex fluoride is preferably in the range of 0.01 to 5 g / L, which content may cause pickling.
  • the value of the total acid GS (TA) of a phosphating solution is preferably in the range from 20 to 200 points, more preferably in the range from 30 to 120 points, in particular from 70 to 100 points.
  • the value of the total acid Fischer GSF (TAF) is preferably in the range from 6 to 100 points, more preferably in the range from 7 to 70 or from 8 to 60 points, in particular at 35 to 55 points.
  • the value of the free acid FS (FA) is preferably 1 to 50 Points, more preferably 2 to 40 points, especially 4 to 20 points.
  • the alternating current may preferably have an amplitude in the range from 0.5 to 30 A / dm 2 , particularly preferably in the range from 1 to 20 A / dm 2 , very particularly preferably in the range from 1.5 to 15 A / dm 2 , in particular in the range of 2 to 8 A / dm 2 .
  • the contactable or contacted anode is used predominantly or wholly in the phosphating solution of the bath and preferably consists of a metallic, electrically conductive material, which - if it dissolves in the phosphating and optionally enriched, possibly as a mud - not the phosphating and not affects the electrolytic phosphating. Therefore, ferrous materials are basically possible, which slowly dissolve in the bath and form iron phosphate-rich sludge.
  • the anode consists of a in the bath solution not or little dissolvable material such as titanium-based, in particular because of the conductivity and possibly low solubility in the bath solution still with a Precious metal of the 8th subgroup of the Periodic Table of the Chemical Elements may be coated.
  • At least one lubricant layer is then applied to the at least one phosphate coating, preferably in a thickness in the range from 1 to 40 ⁇ m, more preferably in the range from 2 to 30 ⁇ m, usually with a coating weight in the range from 1 to 40 g / m 2 , often with a coating weight in the range of 3 to 30 g / m 2 , partly with a coating weight in the range of 5 to 18 g / m 2 .
  • a reactive stearate-containing solution or suspension - as in many wires - results in a layer system that together with the phosphate coating substantially three layers and usually more or less inconsistent.
  • this layer package preferably has a thickness in the range from 2 to 100 ⁇ m, particularly preferably in the range from 4 to 75 ⁇ m, very particularly preferably in the range from 6 to 50 ⁇ m, in particular in the range from 8 to 25 ⁇ m.
  • the optionally at least partially chemically converted phosphate coating and the at least one, optionally partially chemically converted lubricant layer together often have a coating weight in the range of 2 to 100 g / m 2 . The thus coated metallic workpieces can then be cold formed.
  • the metallic workpieces in particular also strips or sheets which are coated with at least one phosphate coating, can then be used in particular for cold forming and / or for the sliding friction insert.
  • at least one substantially organic coating may be applied before and / or after at least one cold working.
  • the wire was switched as a cathode, inserted vertically into the beaker with the phosphating solution and then immediately applied current. After the treatment time, which represents the time of the applied current, the power was turned off and immediately the wire was run, rinsed and dried with compressed air.
  • the titanium anode was switched as the cathode and the wire as the anode, there was only one stain effect, but no well-recognizable coating.
