Phase depth distribution characteristics of the plasma nitrided layer on AISI 304 stainless steel

Structural and magnetic characterization of plasma ion nitrided layer on 316L stainless steel alloy

“…The strain resulting from high nitrogen contents is believed to responsible for the formation of the slip bands in the c N layer. This finding agrees quite well with an earlier study, in which 304 SS was plasma nitrided at 400°C by a low-pressure plasma arc-source ion nitriding method [17]. This study concluded that a high slip band density can be observed on the nitrided surface when the strain resulting from nitrogen supersaturation is great enough to activate the primary {1 1 1} slip system.…”

Nanotribological response of a plasma nitrided bio-steel

“…The well known plasma nitriding (PN) technique is used to improve its mechanical, tribological, corrosion resistance, biocompatibility and life expectancy (Bordji et al, 1996, Xu et al, 2003. The PN technique produces Fe 3 N, Fe 4 N, Cr 2 N and mainly a metastable phase of supersaturating nitrogen in the austenite phase e.g., the expanded austenite, γ N phase (Tromas et ).…”

Effect of plasma immersion ion implantation of nitrogen on the wear and corrosion behavior of 316LVM stainless steel

“…However, despite numerous investigations, the structure and formation of this phase is not completely understood. These results are promising in view of industrial applications, because this treatment on austenitic stainless steel can be performed with techniques using less energetic ions [9][10][11][12] such as low-energy high current density ion implantation [13,14]. Using high current density, it is possible to obtain nitrided layers several micrometers thick.…”
