Plasma nitriding is a widely used technology to enhance the surface performance and extend the service life of alloy parts. The current research mainly focuses on the influences of time, temperature, gas type and pressure parameters on nitriding behavior, while fewer studies have been conducted on the electric potential. This paper mainly reports the effect of the electric potential on nitriding behavior. Test conditions were set using cathodic, anodic and floating potentials in a plasma nitriding furnace. 2Cr13 stainless steel was nitrided at 450°C for 5 h in an NH 3 atmosphere. The experimental results show that the nitriding treatment can be well performed under the different electric potentials, but differences exist in microstructures, morphologies and performance results of the modified layers. The thickness and hardness values of the nitrided layer are ranked as follows: cathodic [ anodic [ floating potential. The anodic nitrided surface has an obvious particle deposition layer composed of nitrides and oxides. Electrochemical and tribological experiments show that the corrosion resistance and wear resistance were significantly improved after a nitriding treatment using the three electric potentials. Moreover, the floating nitriding treatment resulted in the best tribological performance and corrosion resistance.

“…However, direct current plasma nitriding (DCPN) technology, which has been used most frequently at present, is subjected to edge effect and surface arcing 13 . Therefore, active screen plasma nitriding (ASPN) comes as an alternative method to improve the modification of components surfaces [14][15][16][17][18][19] .…”

In this research, AISI 304 austenitic stainless steels were efficient treatment using active screen plasma oxy-nitriding technique. The modified layers were characterized by X-ray photoelectron spectroscopy, X-ray diffraction, scanning electron microscopy, transmission electron microscopes, and atomic force microscopy. In addition, the pitting corrosion resistances of untreated and oxy-nitrided samples were analyzed by polarization method in 3.5 wt.% NaCl solution. The results showed that a duplex-layer consisting of a deposition layer and a diffusion layer (including CrN+α phase and nitrogen expanded austenite phase) was generated. Special concern has been given to the formation of an amorphous top layer for the deposition of nano sized oxy-nitrides. It believed that the deposition layer of oxy-nitrides formed on steel surface during active screen plasma oxy-nitriding that lead to improved corrosion resistance of AISI 304 austenitic stainless steel, so that the pitting corrosive attack can be avoided.

“…The results of the experiments show that the structures of the nitrided layers differ for the different parameters of the mode and this determines the properties of the surface layer. A similar research was done in [8].…”

“…That is why the improved wear resistance of the surface nitrided layer should not be considered separately and outside the context of the complex of operational characteristics of the nitrided parts. In [8] the results for abrasive wear resistance (Kv -relative wear resistance of the test bodies, h -penetration of the counter-body in the nitride zone of the nitrided layer) and the microhardness of the nitrided steels are given. Based on these results, using the method [9], the following significant adequate regression models for the size of the cavity h, which is obtained due to the penetration of the counter-body in the bound zone of the nitrided layer, for microhardness and relative wear resistance are derived.…”

The present research summarises the influence of technological modes based on experimental studies of steels BH11 and BH21 (BS 4659) for hot work in ion nitriding. The peculiarity is that one or several precisely defined modes are not fixed, but a group of parameters from the action of the considered technology in a planned experiment is studied. As a result, the technological modes of ion-nitrided steels are determined, corresponding to the minimal and maximal penetration of the counter-body in the nitrided layer. The obtained results are based on additional research related to microhardness and relative wear resistance. In this way a finished idea of the tribological properties of ion nitrided steels with a specialised purpose is obtained. The tools by which the problem is solved are design of experiments (DOE), modelling and single-criteria optimisation of controlled quantities. The main contribution of the paper is a formalised determination of the influence of the technological parameters of ionic nitriding on the phase composition of the nitrided zone and respectively on the wear resistance of the surface layer.
