Abstract
Die Erfindung betrifft ein Verfahren zur Herstellung einer aktiven Korrosionsschutzbeschichtung auf Bauteilen aus Stahl. Um eine mit herkömmlichen Mitteln (z. B. Tauchen, Spritzen, Fluten) im industriellen Maßstab auftragbaren aktiven Korrosionsschutzbeschichtung für mit Verzunderungsschutz versehene warm umgeformte und insbesondere formgehärtete Stahlteile zu entwickeln, wird im Rahmen der Erfindung Verfahren mit folgenden Verfahrensschritten vorgeschlagen: a. Verwendung eines mit einer Verzunderungsschutzschicht versehenen Stahlelementes, b. Glühen des Stahlelementes bei einer Temperatur über 600°C in einem Glühofen zum Zweck der Härtung, der Halbwarm- oder Warmumformung oder des Formhärtens, wobei eine Reaktionsschicht erhalten wird, c. Aufbringen einer Korrosionsschutzbeschichtung auf die geglühte Reaktionsschicht.The invention relates to a method for producing an active corrosion protection coating on components made of steel. In order to develop an active anticorrosive coating which can be applied by industrial means (for example, dipping, spraying, flooding) for anti-scaling, hot-formed and in particular form-hardened steel parts, the invention proposes processes with the following process steps: a. Use of a steel element provided with a scaling protective layer, b. Annealing the steel element at a temperature above 600 ° C in an annealing furnace for the purpose of hardening, hot or warm forming or shape hardening to obtain a reaction layer, c. Applying a corrosion protection coating on the annealed reaction layer.
Description
Die Erfindung betrifft ein Verfahren zur Herstellung einer aktiven Korrosionsschutzbeschichtung auf Bauteilen aus Stahl.The The invention relates to a method for producing an active corrosion protection coating Steel components.
Bei der Herstellung hochfester Stahlbauteile, wie sie beispielsweise als tragende Karosserieteile im Fahrzeugbau eingesetzt werden, kommen zunehmend Warmumformverfahren zum Einsatz. Eine bestimmte Variante der Warmumformung ist das sogenannte Formhärten oder Preßhärten, bei dem Spezialstähle (meist Mangan-Bor-Stähle) auf Austenitisierungstemperatur erwärmt, umgeformt und im Umformwerkzeug abgeschreckt werden. Dabei entsteht eine mechanisch hochfeste martensitische Gefügestruktur, welche es ermöglicht, durch geringe Materialstärke leichte und dennoch hochfeste Bauteile herzustellen. Die Austenitisierung findet bei Temperaturen oberhalb 850°C statt. Bei dieser Temperatur findet eine starke Zunderbildung auf der Stahloberfläche statt. Diese Zunderbildung erfolgt so schnell, daß selbst Teile, die unter Schutzgasatmosphäre erwärmt werden, z. B. in einem Durchlaufofen, verzundern, sobald sie bei der Überführung vom Ofen in die Preßform mit Luftsauerstoff in Kontakt kommen. Bei den Umformlinien, die für die Stückzahlen einer Fahrzeugproduktion ausgelegt sind, ist es mit vertretbarem wirtschaftlichen und konstruktiven Aufwand nicht möglich, den gesamten Bereich von Erwärmung bis Umformung unter Schutzgas zu betreiben.at the production of high-strength steel components, as for example are used as load-bearing body parts in vehicle construction come increasingly hot forming process used. A specific variant the hot forming is the so-called form hardening or press hardening, for special steels (mostly manganese-boron steels) heated to Austenitisierungstemperatur, reshaped and quenched in the forming tool. This creates a mechanical high-strength martensitic microstructure, which makes it possible due to low material thickness light yet high-strength Produce components. Austenitization takes place at temperatures above 850 ° C instead. At this temperature finds one strong scale formation on the steel surface instead. These Scale formation occurs so fast that even parts that be heated under inert gas atmosphere, for. B. in a continuous oven, scale as soon as they are at the overpass from the oven into the mold with atmospheric oxygen in contact come. At the forming lines, for the quantities a vehicle production are designed, it is justifiable economic and constructive effort not possible the whole range from warming up to reshaping To operate inert gas.
Der sich bildende Zunder neigt zum Abplatzen und ist rauh und spröde. Er beschädigt daher Bauteile sowie Umformwerkzeuge und muß nach dem Formhärten beispielsweise durch Strahlen mit hohem Aufwand vom Bauteil entfernt werden. Durch regelmäßig notwendige Reinigung der Werkzeuge werden die Taktzeiten stark erhöht und der Materialabtrag beim Strahlen muß durch die Verwendung höherer Blechstärken kompensiert werden. In den meisten Fällen werden daher beim Formhärten Stahlbleche eingesetzt, die mit einer Schutzschicht gegen Zunderbildung versehen sind.Of the forming scale tends to flake off and is rough and brittle. He therefore damaged components and forming tools and must after hardening, for example, by blasting be removed from the component with great effort. By regularly necessary cleaning of the tools, the cycle times are greatly increased and the material removal during blasting must by the use of higher Sheet thicknesses are compensated. In most cases are therefore used in the form of hardening steel sheets, the provided with a protective layer against scale formation.

Weiterentwicklung der beschriebenen naßchemischen Verzunderungsschutzschicht,
die Gegenstand der
Ein genereller Vorteil der beschriebenen naßchemischen Verzunderungsschutzschichten gegenüber einer Schmelztauchaluminierung ist, dass bei der Erwärmung auf Austenitisierungstemperatur keine Diffusionsschicht gebildet werden muß und daher kürzere Taktzeiten gefahren werden können. Außerdem besteht hier nicht die Gefahr des Aufschmelzens bei der Erwärmung, so dass auch induktive oder konduktive Verfahren für die Erwärmung beim Formhärten eingesetzt werden können.One general advantage of the described wet-chemical anti-scaling protective layers against a hot dip aluminizing is that at heating to austenitizing temperature no diffusion layer must be formed and therefore shorter cycle times can be driven. It also exists here not the risk of melting during heating, so that also inductive or conductive methods for heating can be used in molding.
