Abstract

Es wird ein Verfahren zur Erzeugung farbiger Oberflächen auf Teilen aus Aluminium oder Aluminium-Legierungen beschrieben, welches durch folgende Verfahrensschritte gekennzeichnet ist:

  • 1. die Teile werden vorbehandelt, indem sie entfettet bzw. ge­ reinigt werden,
  • 2. die Teile werden elektrolytisch anodisch/alkalisch geglänzt,
  • 3. die Teile werden elektrolytisch unter Anwendung von Gleichstrom anodisiert,
  • 4. die Teile werden elektrolytisch und/oder organisch eingefärbt und
  • 5. die Okydschicht der Teile wird verdichtet.
    • A process for producing colored surfaces on parts made of aluminum or aluminum alloys is described, which is characterized by the following process steps:
  • 1. the parts are pretreated by degreasing or cleaning them,
  • 2. the parts are electrolytically anodized / alkaline,
  • 3. the parts are anodized electrolytically using direct current,
  • 4. the parts are colored electrolytically and / or organically and
  • 5. The Okyd layer of the parts is compressed.
