摘要：

Pulsed plasma nitriding (PPN) treatment is one of the new processes to improve the surface hardness and tribology behavior of austenitic stainless steels. Through low temperature treatment (<440 degrees C), it is possible to obtain unique combinations of wear and corrosion properties. Such a combination is achieved through the formation of a so-called "extended austenite phase". These surface layers are often also referred to as S-phase, m-phase or gamma-phase. In this work, nitrided layers on austenitic stainless steels AISI 316L (SS316L) were examined by means of a nanoindentation method at different loads. Additionally, the mechanical properties of the S-phase at different depths were studied. Electron back-scatter diffraction (EBSD) examination of the layer showed a high amount of plasticity induced in the layer during its formation. XRD results confirmed the formation of the S-phase, and no deleterious CrN phase was detected. (C) 2011 Elsevier B.V. All rights reserved.
