Abstract

Verfahren zur Entfernung von zumindest einem Schichtbereich eines Bauteils aus Metall oder einer Metallverbindung Bauteile weisen nach dem Einsatz im Hochtemperaturbereich degradierte Bereiche auf, die durch einen Säureangriff entfernt werden. Der Abtrag bei dieser Säurebehandlung ist jedoch ungleichmässig, da durch die Degradation Bereiche entstanden sind, die ein unterschiedliches Säurelösungsverhalten aufweisen. Durch das erfindungsgemässe Verfahren wird die chemische Zusammensetzung und die Phasenzusammensetzung des Bauteils (1) so verändert, dass ein gleichmässiger Abtrag bei einer Säurebehandlung erfolgt.
