Abstract

Die Erfindung betrifft ein Verfahren zur Herstellung eines beschicht- und/oder fügbaren Blechformteils mit einer Korrosionsschutzbeschichtung (12) umfassend die folgenden Schritte:
- Bereitstellen einer Platine aus einem härtbaren Stahlblechmaterial (10), mit einer wenigstens einseitig aufgebrachten Korrosionsschutzbeschichtung (12);
- Umformen dieser Platine zu einem Blechformteil;
- Ausführen eines Härtevorgangs, um eine Härtung des Stahlblechmaterials (10) herbeizuführen, wobei sich während des Härtevorgangs definiert und zumindest bereichsweise eine temporäre Schutzschicht (13) auf der Korrosionsschutzbeschichtung (12) ausbildet; und
- zumindest teilweises Entfernen dieser temporären Schutzschicht (13) vom Blechformteil durch Reinigungsstrahlen mit einem abrasiven Strahlmittel und/oder durch mechanisches Reinigen, wobei die Korrosionsschutzbeschichtung (12) im Wesentlichen erhalten bleibt.The invention relates to a method for producing a coated and / or available sheet metal part with a corrosion protection coating (12) comprising the following steps:
- Providing a board made of a hardenable steel sheet material (10), with a at least one side applied corrosion protection coating (12);
- Forming this board to a sheet metal part;
- Performing a hardening process, to bring about hardening of the steel sheet material (10), wherein defined during the hardening process and at least partially a temporary protective layer (13) on the corrosion protection coating (12) is formed; and
- At least partial removal of this temporary protective layer (13) from the sheet metal part by cleaning blasting with an abrasive blasting abrasive and / or by mechanical cleaning, the corrosion protection coating (12) is substantially retained.

Die Erfindung betrifft ferner ein Verfahren zum Entfernen einer temporären Schutzschicht von einer solchen Korrosionsschutzbeschichtung.
