Abstract: A method for surface-treating a metallic substrate, in particular steel plate, using a protective coating on a Zn basis, according to which a chloride-containing solution is applied to the protective coating and as a result an anti-corrosion layer comprising hydrozincite and simonkolleite is formed at least in parts. To increase the corrosion resistance of the protective coating and to improve the process sequence and reproducibility of the method, the invention proposes reacting the protectively coated substrate with the solution which, using an acid, is adjusted to a pH of 4 to 6 and contains 1.8 to 18.5% by weight chloride, so as to increase the proportion of simonkolleite in relation to the proportion of hydrozincite in the anti-corrosion layer.

Abstract: The invention relates to a coating mixture for applying a polymeric, corrosion-preventing protective layer to a metallic base for protecting an edge area, a soldered point, a weld seam or a repair point or for sealing the seam of one or more optionally interjoined strips, metal sheets or shaped parts.

Abstract: A method of producing shaped articles made from single-sidedly or double-sidedly galvanized steel sheet, starting from galvanized steel strip, at least one of the steps of the method being a transport operation, and in which, for protection from black-spot corrosion, a corrosion preventive oil is applied which comprises at least one phosphoric acid polyoxyalkylene ester.

Abstract: A method is shown for surface-treating a protectively coated substrate (1), more particularly steel strip, for the purpose of enhancing the strength of adhesion with an adhesive (10), where the at least partly multi-phase protective coat (2) comprises at least zinc and magnesium. In order to provide a particular suitability for adhesive bonding, it is proposed that the protective coat (2) be subjected to a pickling treatment, directed substantially at at least one intermetallic Zn—Mg phase (4) of the protective coat (2), with acidic pickle, more particularly acid.

Abstract: The invention relates to an anti-corrosion system for metals consisting of at least one finish or coating that can be applied to a metal, said finish or coating comprising an organic matrix. The organic matrix also contains anti-corrosion pigments, which are finely distributed throughout the organic matrix. The anti-corrosion pigments are formed from a metal alloy of at least two metals and optionally from inevitable impurities. The invention also relates to a corresponding anti-corrosion pigment.

Abstract: A method is described for joining two sheets (1, 2) of aluminum material on the one hand and iron or titanium material on the other hand by a welding-soldering joint by using a filler, with the iron or titanium material being provided at least in the joining region with a coating preferably on the basis of zinc or aluminum before the filler is applied by forming a weld seam (4) under melting. In order to provide advantageous joining conditions it is proposed that the two sheets (1, 2) are joined in the form of a butt-joint, with the filler on the basis of aluminum being applied for the formation of the weld seam (4) on both sides of the sheet in a region bridging the joint onto the sheet (1) made of iron or titanium material in a width (b) corresponding to at least three times the thickness (d) of said sheet (1).

Abstract: The invention relates to a coating mixture for applying a polymeric, corrosion-preventing protective layer to a metallic base for protecting an edge area, a soldered point, a weld seam and/or a repair point or for sealing the seam of one or more optionally interjoined strips, metal sheets and/or shaped parts. According to the invention, the coating mixture is largely or entirely free of water and/or of organic solvents, whereby it contains at least one radically polymerizable binding agent and at least one compound that forms free radicals when subjected to the action of actinic radiation. This radically polymerizable compound is largely or completely cured with the formed free radicals when subjected to actinic irradiation.
