A method for producing a press-hardened component consisting of a steel sheet or steel strip comprising an aluminum-based coating, and a press-hardened component

摘要

The invention relates to a steel sheet or steel strip for a steel sheet or steel strip, the coating comprising an aluminum-based coat applied by a hot-dip coating method, wherein a cover layer containing aluminum oxide and / or hydroxide is arranged in the coat. It is an object of the present invention to provide an aluminum-based coating which is very suitable for hot forming or cold forming. To this end, the cover layer is produced by plasma oxidation and / or by hydrothermal treatment at a temperature of at least 90 캜, advantageously at least 95 캜 and / or by steam treatment at a temperature of at least 90 캜, advantageously at least 95 캜. Alternatively, the cover layer containing aluminum oxide and / or hydroxide may be produced by anodic oxidation, wherein the coat has a Si content of 8 to 12 wt.%, An Fe content of 1 to 4 wt.%, Lt; / RTI The present invention relates to a method for this, a method for manufacturing a press-hardened component using the same, and an associated press-hardened component.
