Abstract (en)
[origin: EP2290133A1] The method for the production of a steel component provided with a metallic coating protected against corrosion, comprises providing a flat steel product that is produced from steel material containing 0.3-3 wt.% of manganese, where the steel material has an yield strength of 150-1100 MPa and a tensile strength of 300-1200 MPa, and coating the flat steel product with a corrosion protection coating that consists of zinc-nickel (ZnNi) alloy coating consisting of gamma -ZnNi-phase electrolytically deposited on the flat steel product. The method for the production of a steel component provided with a metallic coating protected against corrosion, comprises providing a flat steel product that is produced from steel material containing 0.3-3 wt.% of manganese, where the steel material has an yield strength of 150-1100 MPa and a tensile strength of 300-1200 MPa, coating the flat steel product with a corrosion protection coating that consists of zinc-nickel (ZnNi) alloy coating consisting of gamma -ZnNi-phase electrolytically deposited on the flat steel product, where the coating consists of nickel (7-15 wt.%) and also zinc and unavoidable impurities, heating a board formed from the flat steel product at 800[deg] C amounting to platinum temperature, forming the steel component from the platinum in a form tool and hardening the steel component through cooling at a temperature, in which the steel component exists itself in a condition suitable for forming compensation or hardening structure, with a cooling rate that suffices for forming the compensation structure or hardening structure. The formation of the steel component is carried out as pre-forming and the steel component is formed after heating. The zinc-nickel alloy coating consists of finished steel component of gamma -ZnNi and I ->zinc iron. A manganese-containing layer is present in the finished steel component on the corrosion protection coating, in which manganese is available in metallic or oxidic form. The manganese-containing layer has a thickness of 0.1-5 mu m and the manganese content of the manganese-containing layer is 0.1-18 wt.%. The corrosion protection coating comprises an additional zinc-layer before forming the steel component, where the zinc-layer is applied before forming the steel component on the zinc-nickel alloy coating. The thickness of the zinc-layer is 2.5-12.5 mu m. The corrosion protection coating of the finished steel component comprises a zinc-rich layer lying on the nickel-containing alloy coating. The formation of the steel component is carried out as hot forming and the forming and cooling of the steel component are carried out by a hot forming tool. The formation of the steel component and hardening are carried out in two separated processes. An independent claim is included for a steel component.
