Neues Verfahren entwickelt: Korrosionsmessung von Nanostrukturen unter einsatznahen Bedingungen

(PresseBox) (Saarbrücken, )
Zur realitätsnahen Durchführung von Härtetests an Werkstoffen hat die Arbeitsgruppe um die Saarbrücker Werkstoffwissenschaftler Prof. Horst Vehoff und Dipl.-Ing. Afrooz Barnoush ein weltweit einzigartiges in-situ-Verfahren entwickelt: Dabei werden die zu messenden Materialien mit festigkeitsreduzierendem Wasserstoff „beladen“. Anschließend werden die mechanischen Eigenschaften des Werkstoffes mit einem so genannten Nanoindenter im Mikro- und Nanobereich gemessen. Die neue Methode erlaubt die direkte Optimierung von Werkstoffen auf der Mikro- und Nanoebene unter korrosiver Meerwasserumgebung, versprödender Wasserstoffatmosphäre oder unter dem Einfluss aggressiver Säuren. Mögliche Anwendungen sind die Offshore-Technik, die Wasserstoffenergiewirtschaft oder die chemische Industrie.
