Definitions

  • the invention relates to a method for coating a metallic component with a corrosion protection layer.
  • Fuel savings are especially in the automotive sector increasingly light metal components, eg. B. aluminum or Magnesium used.
  • the components are usually cast, forged, extruded or extruded
  • the metals mentioned and their alloys form one Passivation layer on the surface, taking it under normal climatic conditions protects well against corrosion. Under the influence of corrosion promoting media such as water and Salt, however, these metals are in unacceptable extent attacked corrosively.
  • DE 34 36 846 describes a method for die casting of Light metals, in which for better removal of the component a mold release agent is applied.
  • a mold release agent proposed that metal salts of based on aliphatic carboxylic acids and polyhydric alcohols.
  • the object of the invention is therefore, one opposite the prior art cheaper method for the To provide corrosion protection of light metal components.
  • Light metal components are usually metallic Mold tools using elevated temperatures produced.
  • the molds before the molding process with a mold release agent sprayed.
  • the mold release agent adheres to the surface of the Forming tool and supports the demolding of a molded Component, since the adhesion between the mold and the Component is reduced.
  • the shaping process Commonly used mold release agent is 98% to 99% of water containing between 1% and 2% of an organic Base material based on waxes.
  • the organic Base material of the mold release agent in a surface of the Component burns and significantly reduces corrosion. Under burning here is the emergence of a continuous surface layer during solidification understood the component. This is with the surface of the Component firmly connected and not washable. It has shown that depending on the nature of the basic material Mold release agent with a proportion of organic base material of more than 15% (hereinafter concentrated) Called mold release agent) already acts corrosion inhibiting. The corrosion-inhibiting properties increase with increasing concentration of the mold release agent organic raw material. The best corrosion protection is achieved by the undiluted raw material.
  • the process according to the invention can be used in all shaping processes be applied to light metals in which metallic permanent molds (which may be ceramic or hard metal layers or inserts may have) be used.
  • the molds must during the Forming a temperature of at least 80 ° C, preferably 150 ° C to 400 ° C have a burn-in on the component surface to ensure.
  • molding tools are for this z.
  • the temperature of the mold generally becomes during the molding process at a temperature kept between 150 ° C and 400 ° C. Will that be concentrated Mold release agent on the hot surface of the mold sprayed, so dry the organic materials at least partially on. This has a fixation of the base material to Result and leads to a uniform surface layer on the component surface.
  • the consideration of a Fixing time of up to 30 s is appropriate (claim 5).
  • Particularly suitable for coating by the inventive method are lightweight metal components Aluminum, magnesium, zinc or alloys of these metals (Claim 6).
  • Example 2 shows the use of the method according to the invention for coating a forged component.
  • a housing part for a car accessory from the magnesium alloy AS21 is a corresponding Continuous casting mold with a concentrated mold release agent, the 30% water and 70% organic matter based on glycerol ester, nationwide sprayed.
  • the coating of the component surface by the Mold release agent is continuously after quenching with connected to the surface and solidified, so this ensures permanent corrosion protection. That after the inventive method coated component, and an uncoated, otherwise identical component, was the so-called VDA (Verband Academicr Automobilindustrie) -change test subjected.
  • the VDA change test is taking off a defined series of corrosion tests according to DIN standards together.
  • the components are sprayed with salt for 24 h (according to DIN 50021 SS) and then at 90% relative Humidity a climate change test between 120 ° C and -40 ° C for 96 h (according to DIN 50017 KFW) exposed to and Conclusion under a defined climate at room temperature 48 h held.
  • the visual inspection of the components results in the following:
  • the uncoated component has a surface heavily encrusted with oxides. Fine surface structures are no longer recognizable.
  • the component coated in accordance with the invention remained virtually unchanged; minor surface defects can be recognized only on sharp edges, where the mold release agent was only able to burn into the surface to a lesser extent.
  • a mold release agent is sprayed 85% water and 15% wax Paraffins exists.
  • the mold release agent dries first on the forging tool, resulting in a local fixation of the mold release agent leads.
  • For optimal fixation is a waiting time of about 30 s inserted.
  • An aluminum semi-finished product made of the alloy AlMgSi1 is heated to approx. Preheated 370 ° C and in the forge to a Aluminum component formed in the form of a tension strut. While During the forming process a part of the wax constituent burns of the mold release agent into the surface of the aluminum component on. On the surface of the mold remains sufficient Wax back to ensure removal of the component.
  • Example 1 By coating the aluminum surface with According to the invention baked wax this is from corrosion protected.
  • the component is a corrosion test analogous to from Example 1 subjected. A comparison with one uncoated component of the same design shows the same Result as in Example 1.
