Definitions

  • the invention relates to a coating material for the protection of metals, in particular steel, against corrosion and / or scaling, a method for coating metals and a metal element.
  • Supporting steel parts such as body parts in the automotive industry, are often made of high-strength tempered steels.
  • the steel is transferred by annealing at temperatures above 800-900 ° C in the austenitic region, hot formed and then cooled again with a sufficiently large cooling rate to achieve the formation of a martensitic, high-strength microstructure. If the cooling and thus hardening takes place in the forming tool, this is called form hardening.
  • high-strength components can be produced.
  • For the production of larger components or components with complex geometry is increasingly a two-stage forming process with a preforming at room temperature (cold forming) with downstream hot working (molding) of the preferred Vortexeils used.
  • a general problem with hot forming is the scaling of the steel surface.
  • scaling or scaling is meant the oxidation of metals by direct reaction with atmospheric oxygen at higher temperatures.
  • the scale layer formed on the steel surface is hard and brittle and preferably bursts from the base material when cooled again.
  • the scale layer damages both the components and the forming tools, which must be cleaned of fallen scale after each forming step. With unprotected sheets therefore the form hardening of components with corresponding quantities of series operation is extremely difficult. In addition, the scale must be radiated to achieve adequate corrosion protection before further processing of the components, since it is not a suitable basis for subsequent processes such as phosphating and cataphoretic dip painting.
  • Protective coatings for the corrosion protection of steel are known from the prior art. Metal coatings of aluminum or aluminum alloys and zinc or zinc alloys can be deposited by hot dip or galvanized on the steel.
  • EP 1 013 785 A1 describes the coating of hot-rolled sheet with a metal or a metal alloy. It is a layer of aluminum or an alloy of aluminum, iron and silicon, which is applied by hot dip (Feueralum ist). While such a protective layer provides effective protection against scaling on heating to austenitizing temperature, it is limited in its practical use in press-hardening, which is particularly noticeable when molding complex geometries.
  • DE 102 46 614 A1 mentions that in the dipping method described in EP 1 013 785 A1 an intermetallic alloy phase would form during the coating process between the steel and the actual coating, which would be hard and brittle and would break during cold working. The resulting microcracks would cause the coating to detach from the base material and thus lose its protective function.
  • WO 2005/021820 A1, WO 2005/021821 A1 and WO 2005/021822 A1 describe processes for producing various hardened steel parts.
  • a protective layer consisting of zinc is applied to the steel together with another oxygen-affine element (especially aluminum).
  • This protective layer is described in WO 2005/021821 A1 in a hot-dip method, in WO 2005/021820 A1 and WO 2005/021822 Al applied in a hot dip or galvanic process.
  • a process for the preparation of compositions containing pigments or fillers based on polysiloxanes by means of the sol-gel process is known in which, in a first step, epoxy-containing organosilanes (alkoxysilanes) are hydrolyzed to a sol and the SoI is gelated in a second step using pigments or fillers having an average particle diameter of at least 500 nm and optionally an aromatic polyol having an average molecular weight of at most 1,000.
  • DE 199 40 857 A1 describes a sol-gel coating material for single-layered or multi-layer coated substrates, in particular automobile bodyworks, which should in particular make it possible subsequently to apply a scratch-resistant coating to finished, already cured coatings in as short a time as possible without causing adhesion problems ,
  • a siloxane-containing paint formulation is modified with organic constituents.
  • the sol-gel coating material contains as essential constituents an acrylate copolymer solution and a sol.
  • DE 198 13 709 A1 describes a process for protecting a metallic substrate against corrosion, in which a coating composition based on (hetero) polysiloxanes prepared by hydrolysis and condensation processes is applied to the substrate and cured, the coating composition comprising at least one Species Z, which reacts with the metal to form a species Y, which has a more negative enthalpy of formation than the species X, or interacts.
  • the coating composition can be applied wet-chemically. Weldability or even spot weldability is not described.
  • a process for the coating of metallic surfaces with an aqueous composition which comprises at least one organic Film former containing at least one inorganic compound in particle form and at least one lubricant.
  • the composition of DE 101 61 383 A1 in addition to the organic film former, there is a content of cations and / or hexafluoro complexes of cations and at least one inorganic compound in particle form.
  • DE 101 41 687 Al describes a composition containing silicon compounds which is used essentially for the production of a coating on surfaces and as a raw material for paints. It contains as reaction mixture at least one alkyltialkoxysilane, at least one alkoxysilane and / or at least one tetraalkoxysilane, at least one hydrous silicic acid sol, at least one acid and at least one alcohol or at least one glycol.
  • DE 100 27 265 A1 discloses aluminum coils coated with multicoat color or effect coatings which have on at least one of their surfaces a combination effect layer which consists of a pigmented powder slurry, a clearcoat and a sealer based on organically modified ceramic materials.
  • EP 0 610 831 A2 describes a process for producing functional coatings with organofunctional silanes of a metal compound and low-volatility oxides, wherein a hydrolytic condensation is carried out, for which an organic crosslinkable prepolymer is added to the hydrolytic condensate and the coating solution thus obtained is applied to a substrate and then cured ,
  • WO 95/13326 A1 discloses a process for the preparation of compositions based on hydrolyzable silanes having epoxy groups, in which a prehydrolyzed silicon compound is added with a particulate material, preferably a nonionic surfactant or purely aromatic polyol, to give coatings having a high scratch resistance to obtain long-term hydrophilic properties, corrosion-inhibiting properties, good adhesion and transparency.
  • a prehydrolyzed silicon compound is added with a particulate material, preferably a nonionic surfactant or purely aromatic polyol, to give coatings having a high scratch resistance to obtain long-term hydrophilic properties, corrosion-inhibiting properties, good adhesion and transparency.
  • organic protective coatings are known, for example, protective coatings partially filled with zinc pigments. These provide preferably as an additional seal on a hot dipping process or galvanized steel surface good corrosion protection for low temperature applications, but can not be used for hot forming and molding processes above 800 0 C due to their insufficient temperature resistance. The same applies to a large number of corrosion protection coatings on an organic or sol-gel basis.
  • the applied coating material are provided, that the coating material can be applied wet-chemically, that the coating material changes in high-temperature processes of more than 600 ° C in its structure, and is suitable as a primer for other coating materials.

  • the coating material according to the invention transforms during the high-temperature treatment of a curing process in such a way that electrically conductive reaction layers are formed which weld together with the metal substrate even after treatment at temperatures above 800 ° C. and in particular can be spot-welded.
