    摘要: The invention relates to a method for the production and removal of a temporary protective layer for a cathodic coating, particularly for the production of a hardened steel component with an easily paintable surface, wherein a steel sheet made of a hardenable steel alloy is subjected to a preoxidation, wherein said preoxidation forms a FeO layer with a thickness of 100 nm to 1,000 nm and subsequently a melt dip coating is conducted, wherein, during the melt dip coating, a zinc layer is applied having a thickness of 5 to 20 μm, preferably 7 to 14 μm, on each side, wherein the melt dip process and the aluminum content of the zinc bath is adjusted such that, during the melt dip coating, an aluminum content for the barrier layer results of 0.15 g/m2 to 0.8 g/m2 and the steel sheet or sheet components made therefrom is subsequently heated to a temperature above the austenitizing temperature and is then cooled at a speed greater than the critical hardening speed in order to cause hardening, wherein oxygen-affine elements are contained in the zinc bath for the melt dip coating in a concentration of 0.10 wt.-% to 15 wt.-% that, during the austenitizing on the surface of the cathodic protective layer, form a thin skin comprised of the oxide of the oxygen-affine elements and said oxide layer is blasted after hardening by irradiation of the sheet component with dry ice particles.

    摘要: The invention relates to a method for producing a hardened profiled structural part from a hardenable steel alloy with cathodic corrosion protection. The method includes applying a coating to a sheet made of a hardenable steel alloy, wherein the coating comprises zinc, and the coating further comprises one or several elements with affinity to oxygen in a total amount of 0.1 weight-% to 15 weight-% in relation to the total coating. After applying the coating, the coated sheet steel is roller-profiled in a profiling device. Thereafter, the coated sheet steel is heated to a structural change required for hardening. A skin made of an oxide of the element(s) with affinity to oxygen is formed on the surface of the coating. After sufficient heating the sheet is cooled, wherein the rate of cooling is set in such a way that hardening of the sheet alloy is achieved.

    摘要: The invention relates to a method for producing a sheet metal component. A hot or cold strip is electrolytically coated or coated in a smelting bath and the thus coated hot or cold strip is subjected to a flexible rolling process. During said process, sheet metal having various thicknesses of the flexibly rolled steel strips are produced due to various rolling pressures. Said invention is characterized in that in accordance with the thickness of the sheet metal after being rolled in a flexible manner or in accordance with the rolling pressure during flexible rolling, either the coating whilst being coated has various thicknesses, and in accordance with the rolling pressure with increasing rolling pressure that is expected, the thickness of the coating is thicker and/or the coating prior to or after the flexible rolling is subjected to a mechanical or chemical surface treatment for adjusting the desired emissivity or heat absorption capacity.

The method includes applying a coating to a sheet made of a hardenable steel alloy, wherein the coating comprises zinc, and the coating further comprises one or several elements with affinity to oxygen in a total amount of 0.1 weight-% to 15 weight-% in relation to the total coating. After applying the coating, the coated sheet steel is roller-profiled in a profiling device, so that the sheet tape is formed into a roller-formed profiled strand. Thereafter, the coated sheet steel is brought, at least in parts and with the admission of atmospheric oxygen, to a temperature required for hardening and is heated to a structural change required for hardening. A skin made of an oxide of the element(s) with affinity to oxygen is formed on the surface of the coating. After sufficient heating the sheet is cooled, wherein the rate of cooling is set in such a way that hardening of the sheet alloy is achieved. The invention further relates to a corrosion-protection layer and a profiled structural element.
