Reaktionen von Wasserstoff mit Metallen

von Hubert Hunscheidt

Bei fast allen praktischen Anwendungsfällen des Wasserstoffs kommen metallische Werkstoffe, überwiegend Stähle, zum Einsatz. Unter kritischen Bedingungen kann Wasserstoff in metallische Werkstoffe eindringen und das Werkstoffverhalten entscheidend verändern. Zur Beurteilung einer wasserstoffinduzierten Bauteilgefährdung und zur Ergreifung geeigneter Abhilfemaßnahmen ist die Kenntnis der Wechselwirkung Wasserstoff / Metall eine notwendige Voraussetzung.

Die GfKORR Gesellschaft für Korrosionsschutz e.V. bietet am 6. und 7. September 2022 eine Online-Veranstaltung zum Thema "Reaktionen von Wasserstoff mit Metallen" an. Hier geht es zum Programm.
