Abstract

The embrittlement of metals triggered by liquid zinc, has been known for about 140 years. William H. Johnson [1] stated that iron loses its forming capacity when dipped in melted zinc. Even today, this phenomenon still causes significant damages to hot-dip galvanized steel parts. Here, close attention should not only be paid to the composition of the molten zinc but also to the composition of the steel.

Kurzfassung

Die Versprödung von Metallen, ausgelöst durch flüssiges Zink, ist seit rund 140 Jahren bekannt. William H. Johnson [1] stellte fest, dass Eisen sein Umformvermögen einbüßt, wenn es in geschmolzenes Zink getaucht wird. Dieses Phänomen führt auch heute noch zu erheblichen Schäden an feuerverzinkten Stahlbauteilen. Großes Hauptaugenmerk ist dabei nicht nur auf die Zusammensetzung der Zinkschmelze sondern auch auf die Stahlzusammensetzung zu legen.
