Definitions

  • the invention relates to a layer system for corrosion protection of metallic surfaces, in particular those made of light metals and light metal alloys.
  • the layer system according to the invention can advantageously be used in the corrosion protection of metallic components in the motor vehicle industry.
  • Corrosion protection of metals is an extremely important topic for the metalworking industry in general and especially for the automotive industry.
  • the standards for the motor vehicle industry place high demands on the resistance of the vehicles and vehicle parts with regard to corrosion and pitting.
  • light metal sheets were provided with conversion layers based on chromate, which work in conjunction with KTL (cathaphoretic dip coating) or powder coatings. These conversion layers are used in particular for the viewing area, i.e. for surfaces that are visible to an observer. However, if the light metal substrate underneath is exposed in the event of mechanical damage to the protective layer, the base material is unprotected and exposed to corrosive influences.
  • KTL cathaphoretic dip coating
  • EP 0 323 756 A1 proposes to galvanically deposit a protective layer of zinc or a zinc alloy on these steel sheets, this protective layer preventing corrosion
  • ASSEMBLY SKI contains solid particles which are encapsulated with a thin coating of, for example, Si0 2 , Al 2 0 3 , Zr0 2 or Ti0 2 . Chromates, aluminum compounds, phosphates, molybdenum compounds and titanium compounds are used as corrosion-preventing solid particles.
  • these particles are coated with a material such as e.g. B. Si0 2 , Al 2 0 3 , Zr0 2 or Ti0 2 encapsulated, this material being used to control the surface potential of the corrosion-inhibiting particles and to support their galvanic deposition on a steel sheet.
  • a material such as e.g. B. Si0 2 , Al 2 0 3 , Zr0 2 or Ti0 2 encapsulated, this material being used to control the surface potential of the corrosion-inhibiting particles and to support their galvanic deposition on a steel sheet.
  • the encapsulation increases the resistance to pitting, since the corrosion-preventing ions can diffuse through the capsule material only slowly and so a continuous and uniform release takes place over a longer period of time.
  • corrosion protection is to be provided, with which mechanical damage to the surfaces of light metal components can be securely sealed and protected against corrosive influences.
  • the invention is therefore based on the object of protecting a light metal substrate against corrosion in the case of mechanical damage to the workpiece in a self-healing manner.
  • a corrosion-resistant light metal layer system which contains a substrate made of a light metal and a protective layer is applied to at least one surface of the light metal substrate, the protective layer having microparticles which contain a liquid active substance.
  • microcapsules consist of a polymer shell with an active ingredient contained therein.
  • the microcapsules are destroyed and release the active ingredient contained therein, which protects the damaged area by forming a layer against external influences and thus against corrosion.
  • Substances are used as the active ingredient which, after the microcapsules have been destroyed and released, protect the damaged area from external influences by forming a protective layer on it. Examples of this are paints and inhibitors.
  • the active ingredients must be sufficiently thin to spread quickly and safely over the damaged area and to be able to form the protective layer there.
  • Preferred active ingredients are liquid paints.
  • alkyd resins with long-chain unsaturated fatty acids which can cure only by air oxidation
  • a two-component epoxy resin which can cure by the addition of amine compounds, the two components being present in the layer separately from one another by means of microencapsulation.
  • any polymer that is compatible with the matrix material and that can be applied to the substrate together with the matrix layer material can be used as the capsule shell.
  • the polymer can be a plastic.
  • a preferred capsule material is e.g. B. a Meiamin formaldehyde resin.
  • the capsules can have a diameter in a range from 0.5 to 7 ⁇ m.
  • microcapsules The production of the microcapsules is generally known and can be carried out using conventional encapsulation techniques.
  • all metals which can be electrolessly or electrodeposited on the light metal substrate in question are suitable as the material for the protective layer, in particular copper, nickel and titanium and their alloys, nickel and nickel alloys being particularly preferred.
  • these metals form dispersion layers in which the microparticles or microcapsules are present in dispersed form. Since a direct deposition of the protective layer on a light metal substrate is not possible in most cases due to the electrical potentials, an intermediate layer, usually made of zinc or a zinc alloy, is provided. In the case of zinc or zinc alloy, the intermediate layer is applied using a zincate stain.
  • the layer system according to the invention contains a decorative chrome gloss layer as the top layer.
  • the thickness of the protective layer according to the invention can be selected depending on the application and is usually between 3 ⁇ m and 50 ⁇ m.
  • microcapsules are present in this protective layer in a concentration of usually 5 to 50% by volume. If necessary, this preferred value can of course be exceeded or fallen below. However, if the concentration is too low, the self-healing effect according to the invention can no longer be ensured.

  • FIG. 2b the layer system according to FIG. 2a shows a crack-shaped damage (7) which extends into the aluminum substrate (1) and makes the substrate accessible to external influences.
  • the mechanical action that leads to the crack-shaped damage (7) destroys the microcapsules in the area of the damage and releases their liquid active ingredients. These liquid active ingredients can Place over the surface of the damage and form a layer there that prevents the ingress of moisture and salt, for example. In this way, the layer system according to the invention is quickly and effectively protected against corrosion in a simple manner.
  • the active ingredients are encapsulated in liquid form, they can be distributed over the damaged surface immediately after release and become effective without an upstream dissolution process, as is required for solid particles, which also requires the presence of sufficient liquid.
