Abstract

Die Erfindung betrifft ein Verfahren zur Herstellung wärmebehandelter Blechformteile aus einem Stahlblechmaterial (1) mit einer Korrosionsschutzbeschichtung (12), insbesondere einer im Wesentlichen metallischen Korrosionsschutzbeschichtung, umfassend die Schritte:
- Bereitstellen einer Platine aus einem wärmebehandelbaren Stahlblechmaterial (1), mit der wenigstens einseitig aufgebrachten Korrosionsschutzbeschichtung (12);
- Umformen dieser Platine zu einem Blechformteil;
- Ausführen einer Wärmebehandlung am Blechformteil, zur Veränderung der Werkstoffeigenschaften des Stahlblechmaterials (1), wobei sich während der Wärmebehandlung definiert und zumindest bereichsweise eine Schutzschicht (13), insbesondere eine Oxidschicht, auf der Korrosionsschutzbeschichtung (12) ausbildet.The invention relates to a method for producing heat-treated sheet-metal shaped parts from a steel sheet material (1) with a corrosion protection coating (12), in particular a substantially metallic corrosion protection coating, comprising the steps:
- Providing a board made of a heat-treatable steel sheet material (1), with the at least one side applied corrosion protection coating (12);
- Forming this board to a sheet metal part;
- Performing a heat treatment on the sheet metal part, for changing the material properties of the steel sheet material (1), wherein defined during the heat treatment and at least partially a protective layer (13), in particular an oxide layer, on the corrosion protection coating (12) is formed.

Erfindungsgemäß ist vorgesehen, dass das Verfahren derart ausgeführt wird, dass eine ausreichende Schichtqualität der Schutzschicht (13) im Hinblick auf ein nachfolgendes Beschichten und/oder Fügen des Blechformteils erzielt wird, so dass die Schutzschicht (13) auf dem Blechformteil verbleiben kann.According to the invention, it is provided that the method is carried out such that a sufficient layer quality of the protective layer (13) with respect to a subsequent coating and / or joining of the sheet metal part is achieved, so that the protective layer (13) can remain on the sheet metal part.

Die Erfindung betrifft ferner ein Blechformteil aus einem Stahlblechmaterial (1) mit einer wenigstens einseitig aufgebrachten Korrosionsschutzbeschichtung (12).
