There slightly spherical surfaces are still visible. Sign in to add this to Watch Later. Super Bike What's The Difference? Choose your language. Don't like this video? Verfahren nach. EPB1 en. Therefore, the basis of the above-described prior art, the object of the invention is to provide a method with which is possible to produce steel products with dual metal-coated surfaces in which the second metallic layer better metal on the first formed zinc or zinc alloy layer is adhered as in the prior art. At the same time the formation of an unfavorable for the adhesion of the magnesium or magnesium alloy layer oxide layer on the zinc or zinc alloy layer can also be suppressed that the preconditioning is performed immediately before producing the magnesium or magnesium alloy layer.

    DEC2 en. To prevent the formation of larger amounts of oxides on the surface of zinc or zinc alloy coating, the process sequence in which the preconditioning of the present invention is incorporated, is advantageously carried out in that the pre-conditioning occurs at the generation of the first metallic coating is in direct connection.

    Thus ascorbic acid is a further possibility to precondition the surface of a zinc layer formed by electrolytic galvanizing to a steel substrate, in order to obtain a favorable for the subsequent application of a second metallic layer, coating-free surface area as possible.

    Phosphorus is found only on sample P1 slightly. With the invention, therefore, a method is available that optimally suitable for preconditioning of galvanized steel surfaces for a subsequent application of a magnesium or magnesium alloy layer, in particular in a PVD process. The magnesium or magnesium alloy layer lying on the zinc or zinc alloy layer can be applied by electrodeposition or by a PVD coating process according to the invention preconditioning for example likewise.

    Silber h Wenn daher das Zink Antheile von Schwefelzink enthält, so übt das durch.
    The special feature of this method is that, for the cooling of an aqueous cooling medium is used. The invention relates to a process for coating steel products, in which a surface of the steel product is initially coated with a zinc or zinc alloy coating, and wherein then a magnesium or magnesium alloy layer is applied to the provided with the zinc or zinc alloy layer surface. Dazu wird, wie beispielsweise in W.

    Besonders positiv in Bezug auf die Vermeidung einer Oxidneubildung wirken sich diese Vorkonditionierungsmittel dann aus, wenn es sich bei der Zink- oder Zinklegierungsschicht um eine durch elektrolytisches Verzinken erzeugte Zinkbeschichtung handelt. The preconditioning according to the invention is preferably carried out directly after the metallic coating method, so inline after the generation of the zinc or zinc alloy layer.

    In the use of ascorbic acid as Preconditioning, concentrations have been found in the top of the range specified. In Figure 2a very clearly prominent dark coverings are from the electrolyte of the Tafelverzinkungszelle and based on aluminum.

    In the samples P1, P2, the oxide layer thickness is reduced as compared to the comparative sample Pv.

    The best result shows the rinsed immediately after galvanizing with the more concentrated sample Preconditioning P2.

    In gleicher Weise kann ein Blech beispielsweise auch mit einer Aluminiumbasierten Schicht beschichtet werden. This is clearly seen in the pictures 1c and 1d.

      At the same time the formation of an unfavorable for the adhesion of the magnesium or magnesium alloy layer oxide layer on the zinc or zinc alloy layer can also be suppressed that the preconditioning is performed immediately before producing the magnesium or magnesium alloy layer.

    2. Tojahn:

      The electrolytic deposition takes place in a solvent having a lower acidity than water. The immersion time for sample P1, P2 have been rinsed with the respective Preconditioning, were respectively 10 seconds.
