Definitions

  • Metallic materials are galvanized or cemented to protect them from corrosive environmental influences.
  • the corrosion protection of zinc is based on the fact that it is still less noble than the base metal and therefore initially attracts only the corrosive attack, it acts as a sacrificial layer.
  • the base metal of the galvanized component in question remains intact while it is still completely covered with zinc, and the mechanical functionality is retained for longer periods of time than with non-galvanized parts.
  • thick zinc coatings provide a higher level of corrosion protection than thin layers - the corrosive removal of thick layers takes even longer.
  • GB-A-2 097 024 the treatment of metal surfaces to improve corrosion protection on zinc and zinc alloy surfaces with an aqueous acidic solution comprising an oxidizing agent and at least one metal selected from the group consisting of iron, cobalt, nickel, molybdenum, manganese, aluminum, lanthanum, lanthanide mixtures or cerium ions or mixtures thereof and in particular iron and cobalt ions.
  • an aqueous acidic solution comprising an oxidizing agent and at least one metal selected from the group consisting of iron, cobalt, nickel, molybdenum, manganese, aluminum, lanthanum, lanthanide mixtures or cerium ions or mixtures thereof and in particular iron and cobalt ions.
  • GB-A-2 097 024 the use of trivalent chromium ions and iron ions in combination with an additional metal selected from the group consisting of the abovementioned ions or cerium ions, but mainly describes combinations of chromium (III) in combination with an
  • the present invention has for its object to provide a solution and a method for producing chromium (III) -containing and chromium (VI) -free yellow passivation layers that are color intensive and long-term stability.
  • These metal ions may be added to the reaction solution as soluble salts, preferably as nitrates, sulfates or halides.
  • cobalt (II) ions are contained in a concentration of at least about 0.1 g / L. Their concentration may preferably reach up to 5 g / l.
  • reaction solution can also be used to treat workpieces in accordance with the invention in which, in addition to the zinc or zinc alloy surfaces, surfaces which are not zinc or a zinc alloy, for example iron-containing surfaces such as steel surfaces, are also exposed. These other surfaces can be passivated together with the zinc or zinc alloy surfaces.
  • the reaction solution of the invention also for the passage of aluminum, aluminum alloy surfaces and surfaces made of cadmium.
