“…The direct current plasma nitriding (DCPN) or conventional plasma nitriding (CPN), also known as ionic nitriding is a nitriding process, where the samples to be nitrided receives a plasma discharge [25,37,38]. In this technique, nitrogen atoms are introduced at high temperature (400-650 °C) on the surface of samples [39][40][41][42]. The process transforms the phase composition at the surface of samples.…”

The cathodic cage plasma deposition (CCPD) is an advanced technique recently developed from an active screen plasma nitriding system, which has been used for thin film deposition such as titanium nitride and titanium dioxide (TiO 2). These coatings can improve the physical, mechanical, and optical properties of numerous materials, and such coatings can be developed by several techniques. Unfortunately, the conventional deposition techniques exhibit certain drawbacks, including high cost, the complexity of the operation, very low pressure, and high processing temperature; as a result, CCPD is an advantageous technique. In this review, brief information on the deposition of titanium nitride and oxide coatings on steel alloys, titanium, glass, and silicon substrates, and the effect of control parameters on deposition efficiency is provided. The effectiveness of this system for the synthesis of thin films on various substrates, including insulators and conductors, is also summarized. The recent developments and applications of CCPD for titanium-based coatings are described in detail.

The article will be focused on the analysis of the influence of heat treatment on the nitriding layer, which will be applied on austenitic steel. AISI 304 austenitic steel delivered without heat treatment will be used as experimental material. The nitriding layer will be applied to the austenitic steel samples by plasma nitriding. Then, after plasma nitriding, samples will be subjected to heat treatment. Solution annealing and sensitization will be chosen as heat treatment. Experiments deal with microstructural material analysis, fractographic analysis, mechanical and fatigue tests.

“…The analysis of the plasma nitriding of the welded parts was carried out by Alphonsa et al [11], showing that welded joints using the multiple-pass technique provided better nitriding properties compared with those of the single-pass technique. An improvement in the hardness was also observed by three times which could be correlated with structural changes and process parameters.…”

Analysis of Physicochemical Properties of W1.8507 Steel Parts with Sharp Edges, Thermochemically Treated by Plasma Nitriding with and without Polarized Screens

The plasma nitriding edge effect phenomenon is characteristic of parts with sharp edges. The intersection for the discharge of negative light of the two adjacent faces causes the apparition of this effect. In some cases, this effect causes disturbance to the general process. In this work, a sample with different angles of 30°, 60°, and 90° was analyzed. The sample was subjected to ion nitriding with and without the cathode grid to highlight the reduction of the edge effect on the non-uniformity appearing on the edges and corners of the parts. The effect of the active screen was also analyzed by hardness measurements in the area of the nitride edges and by SEM and EDX analyses in the mentioned areas. Additionally, the influence of active screens was studied by nanoindentation and scratch tests and by measuring the contact angle of coolants and liquid lubricants on the nitride surfaces with both methods.
