Definitions

  • the invention relates to a method for producing a flat steel product with cathodic protection against corrosion.
  • the invention also relates to a plant for the production of a flat steel product provided with cathodic protection against corrosion. Another idea of the invention is a use.
  • coatings are selected as the metallic coating that act as cathodic protection against the steel flat product.
  • Known materials for the coating are, for example, Zn, Al, Mg and alloys of these.
  • Alloys that have been further improved with regard to their suitability as corrosion protection often contain other alloy components, for example in addition to the Ca, Na or Li already mentioned. Due to the high suitability of these elements for oxidation, a hot-dip treatment is not practicable or only with unfavorable results.
  • the invention was based on the object of being able to provide flat steel products with good anti-corrosion coatings despite the obstacles mentioned.
  • the object is achieved with a method for producing a flat steel product with cathodic protection against corrosion.
  • the procedure includes the following steps :
  • a device for gas phase deposition of material is arranged on or in the coating chamber.
  • the device for the gas phase deposition of material is operated to coat a surface of the flat steel product guided through the coating chamber with an anti-corrosion coating.
  • the device for gas phase deposition of material is designed as a PVD coating device.
  • the basic core idea of the invention is that, in contrast to known melt dipping processes, the anti-corrosion coating is applied by applying a material to the surface using a PVD coating process.
  • the use of a PVD coating process has the specific advantage that a coating with a sufficiently high coating rate and diffusion of the particles hitting the surface during the layer formation process is present, that large-area dense and well-adhering anti-corrosion layers can be produced, which surprisingly retain their high quality even under the high stress of a subsequent forming process, in particular hot forming.
  • a thermal pretreatment preferably takes place in step B before the flat steel product is transported into the coating chamber.
  • the thermal pre-treatment includes :
  • the surface coating is therefore particularly preferably carried out on a heat-treated flat steel product, resulting in particularly good layer adhesion.
  • the condition of the layer and the layer adhesion is particularly good when the flat steel product is coated while it is still heated, ie step C is carried out immediately after the heating in step B.
  • a continuous furnace known from practice is used for the heat treatment, with the advantage that a continuous process of a sequence of pretreatment and coating with a potentially high throughput is achieved.
  • step B2 particularly preferably comprises the steps:
  • Pre-oxidation step B2a is carried out in an atmosphere with 0.1 to 10 vol. -Percent 02, preferably 0.1 to 4.0 vol. - Percent O 2 , remainder protective gas , remainder preferably consisting of H 2 and N 2 , remainder particularly preferably consisting of 0 to 10 vol . -percent H2 and 90 to 100 vol-percent N2 .
  • the reduction annealing step B2b is preferably carried out in a protective gas atmosphere containing H2, which is preferably composed of H2 and N2.
  • the atmosphere particularly preferably consists of 0 to 10 vol. -percent H2 and 90 to 100 vol-percent N2 .
  • the reduction annealing step B2b can be supplemented by a subsequent decay anneal, which is carried out at a temperature between 420 and 520 degrees Celsius, preferably with a holding time greater than 30, particularly preferably less than 150 seconds.
  • the end annealing ensures that there is no excessively abrupt cooling during the transition to the subsequent coating step C, thereby avoiding disadvantageous structural changes.
  • dew points of between -15 degrees Celsius and -25 degrees Celsius, for example -20 degrees Celsius have proven to be advantageous.
  • heating ramps and cooling ramps between 5 degrees Celsius/second and 15 degrees Celsius/second are of particular advantage.
  • the flat steel product preferably exits the continuous furnace and into the coating chamber immediately after step B2, and the coating is carried out on the still warm surface of the flat steel product.
  • the temperature of the steel flat product is preferably still close to the pre-treatment temperature, for example between 150 and 250 degrees Celsius for pure zinc systems or between 560 and 710 degrees Celsius for aluminum layers. In general, a temperature between 60 percent and 80 percent of the melting point or alternatively the solidus temperature (all on the Kelvin scale) of the layer is preferred.
  • the anti-corrosion coating is preferably an Al-based or a Zn-based anti-corrosion coating.
