Definitions

  • the invention relates to a method for producing colored surfaces on parts made of aluminum or aluminum alloys.
  • Aluminum parts such as aluminum pressed or rolled profiles, are among others in the building hardware and lighting industry or in particular in the automotive industry with e.g. Window border systems or as decorative frames, moldings and. Like. Used. It is also known to use parts made of aluminum or aluminum alloys that have a colored anodized surface.
  • the new method should be characterized in that a variety of colors with color gradations Gold - bronze Light - dark bronze Gray - brown Gray - blue anthracite Light-dark blue Blue-violet when coloring the parts, a simple check of the coloring results and a reproducibility of the individual color nuances is possible at any time.
  • the oxide layer is permanently pre-compressed.
  • the profile is treated at 70 ° C. in deionized water with the addition of a scale inhibitor of 2 ml / l triazine derivative for 50 minutes.
  • the increase in volume of the layer closes the pores.
  • the layer is now protected against external influences.
