Appraisal of Surface Modified AISI 316 L Stainless Steels

For plasma nitriding treatment, due to Cr 2 N is thermodynamically more stable than CrN, the possibility to produce Cr 2 N increases, and therefore it become the main phase in the nitrided layer in combination with Fe 4 N and Fe 2 N as is showed in the XRD spectrum. In the case of solid nitriding, the nitrogen source, to precipitate chromium nitride, comes mainly Double Glow Plasma Nitriding Pretreatment of TiAlN-Coated Mar 25, 2021 · As a new and efficient plasma nitriding treatment in recent years, Double-glow plasma nitriding (DGPN) pretreatment was used to prepare nitriding transition layer, which adopts Double-glow plasma surface alloying (Xu-Tec process) technology (Ref 14, 15), thus adding a third electrode between the anode and cathode of traditional plasma nitriding Effect of Plasma Oxidation Treatment on Production of a Effect of Plasma Oxidation Treatment on Production of a SiOx/SiOxCyHz Bilayer to Protect the authors found that only the nitriding treatment did not result in a protective layer, once it has a porous structure. deposited without a pre-treatment showed low adhesion to the substrate, demonstrating that the pre-treatment is essential

In this work, triode plasma nitriding (TPN) has been applied to increase the load-bearing capacity of titanium alloys. It is known that the effective adhesion between PVD hard coatings and titanium alloy substrates can be improved significantly after substrate diffusion pre-treatment. Impact of Xe ion bombardment and plasma nitriding on In this contribution we studied the effect of individual and combined surface pre-treatments using Xe ion bombardment and plasma nitriding at low temperatures (380°C) on the adhesion, wear and residual stresses of TiN coatings deposited onto pre-treated 100Cr 6 steel substrates. Ion beam assisted deposition (IBAD) system was used to pre-treat the substrates and deposit the TiN coatings [1]. Nitride passivation of the interface between high-k 3 plasma pre-treatment should be performed at high temperatures (300 C) to fully pre-vent Ge nitride and oxynitride formation at the interface and Ge out-diffusion into the oxide. C-V and I-V spectroscopy results show a lower density of interface traps and smaller gate leakage for samples with plasma nitridation at 300 C.VC 2016 AIP Publishing LLC.

Plasma and Ion Sources in Large Area Coatings:A Review

2. Effects of plasma and ion treatment There are numerous papers [5-11] and textbooks [12-15] on plasma and ion effects and therefore a few notes should suffice here. Emphasis is put on physical vapor deposition (PVD) techniques, although some selected, plasma-enhanced chemical vapor deposition (CVD) will also be mentioned. Pulsed dc discharge in the presence of active screen for 1. Introduction. The dc plasma nitriding (DCPN) is a well - accepted industrial process for the improvement of surface properties such as hardness, wear and corrosion resistance, thus increasing the useful life of the treated piece 1 - 4.It has several advantages over other nitriding techniques such as gas and salt bath nitriding. The Influence of Plasma Nitriding Pre-Treatment on The aim of this study is to investigate the effect of plasma nitriding pre-treatment (PN) on mechanical and tribological behavior of TiN coatings produced by plasma-assisted chemical vapor deposition (PACVD). The heat treatment of quench and temper was carried out on hot work AISI H11 (DIN 1.2343) steel samples. A group of samples were plasma nitrided at 500 °C for 4 h in an atmosphere
