          Kurzfassung

          Das Nitrieren und Nitrocarburieren zeichnet sich durch eine von anderen Verfahren der Randschichttechnik unerreichte Anwendungsvielfalt aus, die sich aus der Struktur nitrierter Randschichten und der Variationsbreite nitrierbarer Werkstoffe ergibt. Die einzigartige Kombination einer dünnen Hartstoffschicht, der Verbindungsschicht, mit einer dickeren, ausscheidungsverfestigten arteigenen Stützschicht ist nur für Nitrierschichten charakteristisch. Beginnend vom Gusseisen über die unlegierten und niedriglegierten Stähle bis zu den hochlegierten nichtrostenden Stählen und hochlegierten pulvermetallurgisch erzeugten Werkzeugstählen sind alle Eisenwerkstoffe nitrierbar. Die optimale Nutzung dieses hohen Eigenschaftspotenzials erfordert die gezielte Erzeugung beanspruchungsgerechter Nitrierschichten durch ein kontrolliertes Nitrieren.

          Abstract

          Compared to other surface engineering technologies nitriding and nitrocarburising is characterized by an unequalled application variety which is based on the structure of the nitrided cases and the multitude of nitridable materials. The for other thermochemical treatments unattainable combination of a ceramic hard coating with non-metallic structure supported by a zone of precipitation hardened α-iron is characteristic only for nitrided cases. All iron materials are nitridable beginning from cast iron and unalloyed as well as low-alloyed steels to high-alloyed stainless steels and high-alloyed powder-metallurgical processed tool steels. The optimal exploitation of the high property potential of nitrided cases required to generate designed surfaces by controlled nitriding.

          Low-temperature gaseous surface hardening of stainless steel: the current status

           Thomas L. Christiansen,  Marcel Somers (corresponding) (2009)
          The present review addresses the state of the art of low-temperature gaseous surface engineering of (austenitic) stainless steel and is largely based on the authors' own work in the last 10 years. The main purpose of low temperature gaseous surface engineering of stainless steel is to develop a hardened case at the surface, while maintaining the superior corrosion performance. This can be achieved by dissolving colossal amounts of nitrogen and/or carbon without forming nitrides and/or carbides, thus developing so-called expanded austenite. The present work gives an overview over results obtained on homogeneous expanded austenite and covers the crystallography for nitrogen- and carbon-stabilised expanded austenite, the solubility for nitrogen and carbon, the diffusion of these interstitials as well as the stability of expanded austenite with respect to nitride and carbide formation. Subsequently, the fundamental understanding acquired on homogeneous samples is applied to understand the morphology, composition, and residual stress distribution in functionally graded material, as obtained by nitriding, carburising or nitrocarburising of austenitic stainless steel. Thereafter, aspects of modelling the compositional changes occurring during nitriding are addressed. The overview summarises with an outlook towards future scientific challenges.
