T. Frączek, M. Olejnik, Częstochowa University of Technology, Częstochowa Poland An analysis of the infl uence of diff erent parameters of the ion nitriding process conducted in a H2 + N2 atmosphere on the properties of the surface layer of Grade 2 titanium was carried out in the study. This allowed a model for ion nitriding of technical titanium to be developed. The equipment used in the exper...

Paper presents the research of austenitic steel AISI 304after ion nitriding at 400◦C and at t =4h, for the two different variants of samples distribution in the working plasma reactive chamber tube. In order to assess the effectiveness of ion nitriding variants emission spectroscopy – GDOES, surface hardness tests, microstructure research (LM) of nitrided layers were made. It has been found tha...

M. Ogórek, Z. Skuza, T. Frączek, Czestochowa University of Technology, Czestochowa, Poland The study examined layers were formed on the outer surface of austenitic stainless steel 304 under glow discharge conditions in the low-temperature and short-term ion nitriding. The outer layers analyzed in the work produced in parallel in the classical process of cathode and a novel method of “active scr...

2014 Modelling of plasma reactors for steel surface nitriding has been achieved in discharge and postdischarge conditions of N2 flowing gas. Diagnostics and calculations have been focused on the N2(X, V) vibrational molecules and N atoms which are the most populated long living species. It has been demonstrated that these neutral active species produce steel surface nitriding with the same char...

diffusion of nitrogen in plasma nitrided iron and structural evolution during the nitriding process were evaluated by several characterization techniques including optical microscopy (om), microhardness depth profiling (hdp), scanning electron microscopy (sem), x-ray diffraction (xrd), glow discharge optical emission spectroscopy (gdoes), and secondary ion mass spectroscopy (sims). plasma nitri...
