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...

Plasma nitriding is a method of surface modification using glow discharge technology to introduce nitrogen into the metal, which subsequently diffuses material. The main advantages plasma over conventional processes are: reduced cycle time, controlled growth layer, elimination white distortion, no need finishing, pore-free surfaces and mechanical masks instead copper plating. process especially...

Plasma nitriding was performed to suppress hydrogen uptake and permeation in pure iron. The influence of the phase structure nitrogen compound layer on behaviors examined. could be controlled by changing gas composition N2-H2 plasma. layers consisting ε-Fe2-3N γ'-Fe4N with a thickness 4.9 µm, 2.0 µm were formed plasma this study. During tests, resulted small current values compared as-polished ...
