Abstract

This contribution provides an overview of the concepts of high temperature solution nitriding (HTSN) and the state of the art of the technology. It shows how HTSN can be applied to different classes of stainless steels. New advances of HTSN are presented, in particular the combination of HTSN with low temperature surface hardening, LTSH, is addressed: HTSN is an excellent “pre-treatment” for LTSH for austenitic, duplex, ferritic and martensitic stainless steels. Examples of combined HTSN + LTSH treatments of duplex and martensitic stainless steels are shown.

Kurzfassung

Dieser Beitrag bietet einen Überblick über die Konzepte des Hochtemperatur-Randaufstickens (HTSN) und den Stand der Technik. Er zeigt, wie HTSN auf verschiedene Klassen von Edelstählen angewendet werden kann. Neue Fortschritte von HTSN werden vorgestellt, insbesondere die Kombination von HTSN mit Niedertemperatur-Oberflächenhärtung (LTSH) wird erörtert: HTSN ist eine ausgezeichnete „Vorbehandlung“ für LTSH für austenitische, Duplex-, ferritische und martensitische Edelstähle. Es werden Beispiele für kombinierte HTSN + LTSH-Behandlungen von Duplex- und martensitischen Edelstählen gezeigt.
