Definitions

  • the invention relates to the corrosion protection of metallic materials, in particular of those which are provided with a conversion layer.
  • the coating of the metallic workpiece to be protected with a coating of another metal is a widely used and established method in the art.
  • the coating metal can behave in the corrosive medium either electrochemically nobler or less noble than the material base metal. If the coating metal behaves less noble, it acts in the corrosive medium compared to the base metal as a sacrificial anode (cathodic corrosion protection).
  • this protective function associated with the formation of corrosion products of the coating metal is thus desired, the corrosion products of the coating often lead to undesirable decorative and often also to functional impairments of the workpiece.
  • cathodically protective base coating metals such as, for example, Zinc or aluminum and their alloys often used so-called conversion coatings.
  • conversion coatings These are reaction products of the non-noble coating metal which are insoluble in aqueous media over a wide pH range with the treatment solution. Examples of these so-called conversion layers are so-called phosphating and chromating.
  • the layer to be protected is immersed in an acidic solution containing phosphate ions (see, for example, US Pat WO 00/47799 ).
  • the acidic medium leads to the partial dissolution of zinc from the coating.
  • the liberated Zn 2+ cations form a sparingly soluble zinc phosphate layer on the surface with the phosphate ions of the treatment solution. Since zinc phosphate layers themselves form only a comparatively bad corrosion protection, but an excellent primer for For this applied paints and paints, their main application is in the function of a primer for coatings and paints.
  • chromium (VI) ions see EP 0 553 164 A1 .
  • chromium (VI) is reduced to chromium (III), which in the surface film which is more alkaline by the evolution of hydrogen, inter alia as chromium (III) hydroxide or as sparingly soluble ⁇ -oxo or ⁇ -hydroxo bridged chromium (III) Complex is deposited.
  • chromium (III) hydroxide inter alia as chromium (III) hydroxide or as sparingly soluble ⁇ -oxo or ⁇ -hydroxo bridged chromium (III) Complex is deposited.
  • sparingly soluble zinc chromate (VI) is formed. Overall, a tightly closed, very well protects against corrosion attack by electrolytes conversion coating on the zinc surface.
  • chromium (VI) compounds are acutely toxic and highly carcinogenic, requiring replacement of the methods associated with these compounds.
  • a disadvantage of this additional process step using polymer dispersions is the occurrence of drainage drops in the coating of workpieces produced on the frame and / or the bonding of coated bulk material;
  • problems such as dimensional accuracy of threads and the like are associated with the layer thickness of these organic sealants. If such sealings have a high degree of corrosion protection, the adhesion to the coated substrate is generally very good. This also means a very good adhesion to machine parts of the coating equipment, what their Cleaning difficult. Goods with coating defects, which should again go through the entire coating process, also has to be stripped of costs again, which usually requires an additional process step.
  • the JP 2005 023372 A describes a passivating post-treatment for zinc surfaces provided with a conversion coating.
  • a zinc surface was provided with a black passivation based on Cr (III) and Co.

  • the cited document also describes the addition of water-soluble polymers such as polyacrylates to the treatment solution.
  • the object of the invention is to provide processes for increasing the corrosion protection of metallic, in particular zinc-containing, surfaces provided with conversion layers.
  • the aim is to preserve or improve the decorative and functional properties of the surfaces.
  • the above-mentioned problems in the use of chromium (VI) -containing compounds or post-treatments with polymer dispersions should be avoided.
