摘要： A method for the production of metal sheet including a substrate having two faces, at least one of which is coated with a metal coating including between 0.1 and 10% by weight of Mg and optionally between 0.1 and 20% by weight of Al, the remainder of the metal coating being Zn. The method includes at least the steps of providing a steel substrate having two faces, depositing a metal coating on at least one face hot dipping of the substrate, solidifying the metal coating, applying onto the outer surfaces of the metal coating an aqueous solution having a pH of 7 to 13 and including a magnesium ion complexing agent, for which the dissociation constant pKd of the complexing reaction of the agent with the magnesium is greater than or equal to 2, and to the metal sheet obtainable with this method.

摘要： A method for producing a metal sheet is provided. The method includes providing a steel substrate having two faces, depositing a metal coating on each face by dipping the substrate in a bath, cooling the metal coatings, altering layers of magnesium oxide or magnesium hydroxide formed on the outer surfaces of the metal coatings, and depositing a layer of oil on the outer surfaces of the metal coatings.

摘要： A method for the manufacture of a hardened part coated with a phosphatable coating is provided. The method includes providing a steel sheet pre-coated with a metallic coating including from 4.0 to 20.0% by weight of zinc, from 1.0 to 3.5% by weight of silicon, optionally from 1.0 to 4.0% by weight of magnesium, and optionally additional elements chosen from Pb, Ni, Zr, or Hf, the content by weight of each additional element being less than 0.3% by weight, the balance being aluminum and unavoidable impurities and residuals elements. The steel sheet is cut to obtain a blank, the blank is thermally treated at a temperature between 840 and 950° C. to obtain a fully austenitic microstructure in the steel, the blank is transferred into a press tool and hot-formed to obtain a part. The part is cooled to obtain a martensitic or martensitic-bainitic microstructure or made of at least 75% of equiaxed ferrite, from 5 to 20% of martensite and bainite in amount less than or equal to 10%.

摘要： A metal sheet is provided. The metal sheet includes a substrate having two faces, each face hot dip coated with a metal coating of zinc, aluminum and magnesium. The metal coatings include between 0.1 and 20 wt % of aluminum and 0.1 and 10 wt % of magnesium. Layers of magnesium oxide or magnesium hydroxide are formed on outer surfaces of the metal coatings. The layers are altered by applying an acid solution on the outer surfaces of the metal coatings or by applying mechanical forces using a roller leveler, a brushing device, or a shot-blasting device on the outer surfaces of the metal coatings. The metal sheet also includes a layer of oil deposited directly on the outer surfaces of the metal coatings.
