“…In the block-on-ring configuration friction test, the minimum value of wear rate was observed for γN-rich specimens. As the other authors, Wang et al (2009) stressed that increasing concentration of CrxN in the reaction layer results in decrease in drysliding wear resistance. Reduction of AISI 304L wear rate after nitriding was also emphasized by Menthe et al (2000).…”

“…In temperatures exceeding 420°C, due to sufficient diffusivity of chromium in the austenite the precipitation of CrxN starts (Tab. 1, 2), resulting in depletion of Cr from austenitic matrix and, usually, decrease in corrosion resistance (Wang et al, 2009). Unfortunately, the rate of plasma nitriding processes and nitrogen diffusion in temperatures below 450°C is low and leads to a very long duration of the nitriding process for getting appropriate layer thickness (Wang et al, 2013).…”

“…Foerster et al (2007) noticed that in dry sliding tests with WC-Co ball as a counter sample glow discharge ion nitriding reduced the friction coefficient with respect to untreated sample. According to Wang et al (2009), the DC plasma nitriding significantly improves dry-sliding wear resistance also of AISI 304L steel. In the block-on-ring configuration friction test, the minimum value of wear rate was observed for γN-rich specimens.…”

Nowadays, the improvement of ferrous materials performance is a problem of high interest. One of well-known wear-and corrosion properties improving technique is plasma nitriding, in which elemental nitrogen is introduced to the surface of a metal part for subsequent diffusion into the material. As a result, a compound, "white" layer and a diffusion zone are formed at the detail's surface. Most of the authors positively describe the effects of surface ion nitiding. On the other hand, there are also reports on adverse effects of direct current and pulsed direct current plasma nitriding on ferrous materials performance. Therefore, an attempt to provide comprehensive summary on direct current and pulsed direct current ion nitriding and its influence on ferrous materials' mechanical and corrosion properties has been made. According to the results, some of the technique drawbacks are hard to avoid in mass production.

“…Below the eutectoid temperature nitriding and nitrocarburizing that prevent dimensional distortions are usually applied. Because of the existence of oxidizing species (H 2 O and CO 2 ) in the gas nitrocarburizing atmosphere, the process held at sub-critical temperature for Fe-N system in ammonia (NH 3 ) and carbon dioxide (CO 2 ) is called oxy-nitrocarburizing (ONC) [1].…”

Abstract. The thermochemical treatments of tool steels improve the performance of the components with respect to surface hardness, wear and tribological performance as well as corrosion resistance. Compared to the conventional gas ferritic nitrocarburizing process, the original vacuum oxy-nitrocarburizing is a time-, cost-effective and environmentally-friendly gas process. Because of the oxidizing nature of the gas atmosphere, there is no need to perform subsequent post-oxidation.In this study, a vacuum oxynitrocarburizing process was carried out onto four tool steels (AISI H10, H11, H21 and D2) at 570 °C, after hardening and single tempering. The structural analysis of the compound and diffusion layers was performed by optical and electron microscopy, X-ray diffraction and glow discharge optical emission spectrometry (GDOES) methods. A largely monophase İ-layer is formed with a carbon accumulation at the substrate adjacent area. The overlaying oxides adjacent to the İ-carbonitride phase contained Fe 3 O 4 (magnetite) as a main constituent. A thermodynamic modelling approach was also performed to understand and optimize the process. The "Equilib module" of FactSage software which uses Gibbs energy minimization method, was used to estimate the possible products during vacuum oxynitrocarburising process.
