“…The cathodic potential treatment resulted in the appearance of phases of vanadium nitride-II (VN 2 ) -ICSD 144473, iron nitride-III (Fe 3 N) -ICSD 080930, and iron nitride-IV (Fe 4 N) -ICSD 060195. As in other cases 20,25,44 , the formation of these primary iron nitrides was expected. The emergence of the VN 2 phase is related to the CCPD deposition process in which the cage material undergoes sputtering.…”

“…These techniques come with limitations, such as environmental issues 16 , low deposition efficiency 17 , and unsuitability for large-scale processing 18 , due to complex equipment and high costs 19 . In conventional plasma nitriding, samples are treated at a cathodic potential, directly bombarded by high-energy plasma ions, allowing nitrogen to react with the metallic material's surface, forming a hardened layer of nitrides 20 . During this process, ion-surface interactions can sometimes lead to overheating 21 , edge effect, and hollow cathode effect due to the high cathodic potential on the sample's surface [22][23][24] .…”

“…Simultaneously, a hard nitride layer forms beneath the deposited film due to the diffusion of implanted nitrogen atoms into the sample. This layer can act as a barrier to the diffusion of unwanted interstitial elements (oxygen and its oxides) 20 . Due to the absence of direct ion bombardment on the sample surface, it is possible to reduce or eliminate overheating and edge effects.…”

In this study, nanostructured coatings of VN 2 /Fe 3 N/Fe 4 N are synthesized by Plasma Deposition (CCPD) using a vanadium cathodic cage and subject to cathodic and floating potential treatments. Microstructural and mechanical properties of coated SAE 1080 steel samples are investigated using X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Vickers microhardness (HV), and surface roughness analysis. The coating produced under cathodic potential treatment exhibited a nitridebased microstructure (VN 2 , Fe 3 N, Fe 4 N), with surface morphology consisting of clusters of granular structures with varied particle sizes. The coating produced under floating potential predominantly exhibited the iron nitride phase (Fe 3 N) with a morphology composed of uniformly sized grains. Microhardness testing showed that both layers exhibited more excellent plastic deformation resistance than the substrate. Roughness measurements confirmed a more organized microstructure profile for the sample treated under floating potential. This study demonstrates that the CCPD-produced cathodic potential coating can be utilized in tribological applications.

“…30 Previously, 31 this system was used for synthesising molybdenum oxide and zinc oxide coating on steel, with excellent mechanical and tribological performance. Recently, 32 the combination of plasma nitriding and CCPD (equipped with niobium and vanadium cathodic cages) has been reported in alternating order to improve the surface properties of AISI D2 tool steel. The combined treatment provides an improvement in hardness and wear resistance.…”

AISI-420 martensitic steel is used in several applications due to its high corrosion resistance. A niobium nitride coating is deposited on steel by cathodic cage plasma deposition (CCPD) to upgrade the surface properties. The X-ray diffraction shows that the coating has a tetragonal Nb4N5 structure in each condition. The nano-hardness of the untreated sample (2.5 GPa) is increased up to 15.5 and 18.7 GPa at 400°C and 450°C, respectively. A ball-on-disc wear tester is applied for wear analysis, and the wear rate is found to be reduced up to six times by coating. This study shows that the CCPD can be used successfully for depositing niobium nitride coating with outstanding mechanical and tribological properties of AISI-420 steel.

“…Much research [11,12] has been focused on composite treatment techniques combining mechanical and thermochemical surface modifications, but for many workpieces experiencing wear, these approaches cannot achieve the desired mechanical improvements. Therefore, composite thermochemical surface modification [13][14][15][16][17][18] is a more promising approach. Vacuum carburizing is superior to conventional carburizing in terms of throughput, control lability, surface property enhancement, etc.…”

In this study, the responses of 20CrNi2Mo steel to carburizing (C) and carburizing-nitriding (C+N) duplex treatment and the effects of these treatments on the friction and wear properties were systematically studied. The 20CrNi2Mo surface layers were characterized by optical microscopy (OM), laser scanning confocal microscopy (LSCM), X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Vickers microhardness tests and high-speed reciprocating friction and wear testing. The results showed that after the carburizing and nitriding duplex treatment, an approximately 5 μm-thick compound layer (CL) consisting of the γ′-Fe4N and ε-Fe2-3N phases had formed on the surface, and the diffusion layer depth was approximately 220 μm. The carbides (MC) stored during carburizing were easily converted to nitrides (MN) during the nitriding process. Furthermore, the surface microhardness (879 HV) was increased by a factor of 2 compared with the substrate (420 HV), the surface residual compressive stress (-652 MPa) was increased significantly, and the surface roughness also increased. Wear analyses under different loads showed that specimen C exhibited the worst wear resistance, and its wear mechanism was mainly abrasive wear. The C+N with CL samples showed excellent wear resistance under a 20-N load; after removing the CL samples (C+N with CL), they showed excellent wear resistance under a 40-N load, and the wear mechanism was mainly adhesive wear. This work showed that the wear resistance was improved significantly by the carburizing and nitriding duplex treatment, but the CL had different effects on the wear performance under different loads.
