Abstract
Color etching provides additional information that standard etchants do not or only insufficiently reveal – in different steels but also in virtually all non-ferrous metals.
This works aims at presenting the possibilities this technology provides by using the examples of aluminum, copper, nickel, titanium materials, and cast iron, while also pointing out its limits.
Kurzfassung
Nicht nur im Bereich der verschiedenen Stähle, sondern auch bei nahezu allen Nichteisenmetallen lassen sich mit Hilfe der Farbätztechnik Zusatzinformationen erhalten, die die Standardätzmittel nicht oder nur unzureichend aufzeigen.
In diesem Beitrag sollen anhand von Beispielen an Aluminium-, Kupfer-, Nickel- und Titanwerkstoffen sowie an Gusseisen die Möglichkeiten dazu gezeigt werden aber auch auf die Grenzen dieser Technik hingewiesen werden.
