Definitions

  • the invention relates to a method for producing and removing a temporary protective layer for a cathodic coating on carrier metals.
  • a method for removing a layer of a component is known.
  • This is a layer of organic binder that is to be removed from a substrate without damaging the substrate.
  • a jet of dry ice particles is guided over the surface, so that material is removed from the layer containing an organic binder by the action of the occurring dry ice particles.
  • the removal of dry ice is intended to prevent contamination by foreign substances and to not impair the metallic basic body of the component.
  • a method for removing a metal layer wherein a layer system comprising the metal layer and a substrate coated by the metal layer and the removal process is a blasting process.
  • the blasting process can be a sandblasting process, whereby the metal layer is strongly cooled in order to achieve low-temperature embrittlement of the layer with respect to the substrate.
  • a method and an apparatus for irradiating with different blasting agents are known.
  • an abrasive blast treatment with blasting agents in which the abrasive effect of the blasting agent is between the blasting agents present in fluid form under normal conditions and the blasting agents present in solid state under normal conditions.
  • a mixture of a first blasting agent such as dry ice and a second abrasive blasting agent such as sand is used.
  • an apparatus and method for removing a coating from a substrate which is said to be gentle on materials and suitable for removing both soft and hard coatings.

  • a method and apparatus for removing layers formed by heating and cooling on pieces of metal are known. Because when removing, for example, scale, oxydsilicate and slag layers on metal workpieces and especially metal workpieces with non-planar surfaces, such as axle and bodywork components for vehicles, the solid particles in abrasive pressurized gas jets are not intended to completely remove metal workpieces from the compressed gas flow with the aid of, for example, dry ice particles be applied to the metal workpiece to be cleaned, preheated and have a temperature which is greater than the temperature of the air surrounding the metal workpiece and / or as the surface temperature of the metal workpiece.
  • the layers to be removed from the surface of the piece of metal are removed by the mechanical action of the high velocity impacting dry ice particles and by the localized cooling of the surface and the layer due to the dry ice particles.
  • the addition of the oxygen-affine elements causes the oxygen-affinity elements diffuse from the composition of the cathodic protection layer to the surface and form there a very fine protective layer.
  • This very fine protective layer may for example consist of magnesium oxide or aluminum oxide or mixtures thereof. From the WO 2005/021820 It is also known to apply such a method in roll profiling.
  • the object of the invention is to provide a method with which the paint adhesion can be improved on provided with a cathodic protective layer hardened steel components.
  • the paint adhesion may not be optimal with cathodic anticorrosion coatings provided with a fine surface protection coating.
  • there is no alternative to the formation of these thin layers since otherwise only a post-galvanizing of these components could be carried out, which is very complex and expensive.
  • the fine protective layer of one or more oxygen-affine elements is formed so that it can be removed again, ie only temporarily present, in order to protect the cathodic layer during heating above the austenitizing temperature, ie. H. of the glow, to ensure.
  • this thin protective layer is formed from at least one oxide of the oxygen-affine elements in such a way that cracks and / or defects form in this layer. These cracks allow to detach the scales of the oxide limited by the cracks and / or defects by means of dry ice irradiation.
  • the radiation is carried out only with dry ice without additives, wherein the dry ice particles penetrate through the cracks and / or defects in the cavities under the protective layer and sublimate under up to 800-fold volume increase.
  • the potentially loose or to be dissolved particles from the oxide of / the oxygen-affine elements / element along with any zinc oxide particles thereon are blasted off.
  • the extra thermal shock from the cryogenic Dry ice particles lead to further thermal stresses in the oxide / oxygen-sensitive element / element layer and thus support the desired removal.
  • an abrasive removal should and must be avoided, as this attacks the cathodic protective layer.
  • the thickness and the crackiness of the fine protective layer of the oxide of the / the oxygen affinity elements / elements arrive at the pretreatment of the bare steel strip and its influence on the interfacial kinetics or formation between zinc and steel substrate in the hot dip coating and on the zinc deposit.
  • An inhibiting layer is a layer which occurs as a result of aluminum addition in the zinc bath between the steel substrate and the zinc layer during the continuous hot-dip coating and, if appropriate, subsequent heat treatment.
  • the object of the inhibition layer in general is to brake an excessively strong alloy or reaction between iron and zinc.
  • FIG. 1 The surface in which the Al 2 O 3 protective layer shows cracks and / or defects as a result of the heat treatment or hardening is ideally to be cleaned with dry ice.

  • both the ripple the iron-zinc layer is lower and the Al 2 O 3 layer has larger closed areas that go beyond the cavities caused by the waviness of the iron-zinc layer. Accordingly, little zinc oxide is formed in the region of the cracks. Since parts of the cavities are covered by the Al 2 O 3 layer, it is not possible to cause blistering by sublimation in the cavities.

  • FIG. 4 shows the surface after curing in the case of a thick inhibitor layer formation and / or too high a zinc deposit. Since the Al 2 O 3 protective layer is comparatively thin in this case, the electron beam can penetrate it more easily. The cavities located under the Al 2 O 3 protective layer are therefore recognizable in the recording as dark areas, since less backscattered electrons from the Al 2 O 3 protective layer contribute to the detector signal.

  • FIG. 6 is the surface after FIG. 4 after performing the dry ice cleaning process.
  • the darker areas show uncoated Al 2 O 3 and a surface that only allows poor paintability.
  • the inventive method is in FIG. 7 in which dry ice particles are brought onto the Al 2 O 3 layer with a dry ice blasting gun, enter the cavities and sublimate there.
  • a dry ice blasting gun enters the cavities and sublimate there.
  • Al 2 O 3 flakes are removed together with zinc oxide constituents adhering to them, so that the roughness of the iron-zinc layer (see US Pat FIG. 5 ) stays behind.
  • the pretreatment and hot-dip coating is performed so that in the pre-oxidation a FeO layer is greater than 100 nm but less than 1000 nm and preferably forms an inhibiting layer having an aluminum content of 0.15 g / m 2 to 0.4 g / m 2 has.
