Effect of plasma nitrocarburizing on fatigue behaviour of AISI 1020 steel
, 2008 AISI 1020 steel was plasma nitrocarburized under different process parameters regarding time (1, 4 and 12 h), temperature (500, 570 and 640 degrees C) and different CO2 ratio. The fatigue strength of plasma nitrocarburized AISI 1020 steel has been assessed by using a rotating bending fatigue machine and observed by scanning electron microscopy (SEM ...

Process control of plasma nitriding and plasma nitrocarburizing in industry
Surface and Coatings Technology, 1993Abstract Whenever plasma processes are used under continuous production conditions to produce nitrided or nitrocarburized layers, a variety of parameters has to be controlled in order to guarantee consistency of quality. Some of these parameters must be considered during the engineering period of an installation.

Plasma post-oxidation process for nitrocarburized layer
Surface and Coatings Technology, 2000Abstract In the process of the formation of a nitride/oxide layer, the effects of H 2 gas on the oxidation process have been investigated in both a conventional steam process and a plasma oxidation process. In a conventional steam process a single phase of magnetite (Fe 3 O 4 ) has been obtained below a H 2 O/H 2 volume ratio of ∼1:2 while a single

Duplex treatments of plasma nitrocarburizing and post-oxidation in an adiabatic plasma furnace
Surface and Coatings Technology, 2007Abstract The duplex treatments of plasma nitrocarburizing plus post-oxidation have been carried out in a self-made adiabatic plasma furnace. The sample material is medium carbon steel AISI 1045. The compound layers are made up of Fe 3 O 4 oxide layer, Fe 2–3 N compound layer and Fe 4 N diffusion layer.

Plasma (Ion) Nitriding and Nitrocarburizing of Steels
2013AbstractPlasma (ion) nitriding is a method of surface hardening using glow-discharge technology to introduce nascent (elemental) nitrogen to the surface of a metal part for subsequent diffusion into the material. This article describes the procedures and applications of plasma nitriding methods of steel.

Effect of Methane Addition on Formation of Plasma Nitrocarburized Layers
Metallography, Microstructure, and Analysis, 2016Plasma nitrocarburizing is a thermochemical process that can be used to improve the mechanical properties of metal surfaces by enriching them with carbon and nitrogen atoms. The quantity of carbon in the plasma primarily affects the formation of the microstructure of the compound layer.

Plasma post-oxidation of nitrocarburized SUM 24L steel
Materials Science and Engineering: A, 2007Abstract Plasma nitrocarburizing and plasma oxidizing treatments were performed to improve the wear and corrosion resistance of SUM 24L steel. Plasma nitrocarburizing was conducted for 3 h at 570 °C in the nitrogen, hydrogen and methane atmosphere to produce the ɛ-Fe2–3(N, C) phase.
