The mechanism of plasma nitriding include the formation of various active species generating nitrogen atoms reacting with the metal. Which species prevail in supplying nitrogen depends on nitriding conditions as well as the nature of the treated meta
The surface of irons and steels can be hardened by introducing nitrogen (nitriding), nitrogen and carbon (nitrocarburizing), or nitrogen and sulfur (sulfonitriding) into the surface. This article lists the principal reasons for nitriding and nitrocar

Two cast irons, pearlitic-ferritic gray and ferritic ductile, were plasma and gas nitrocarburized at the same temperature and for the same processing time to produce a compound zone of about 10-14 μm thick. It was demonstrated that both processes ca

The fundamentals of plasma nitriding and nitrocarburizing are described, including the direct current (DC) and pulse glow discharge plasma, generation of the active nitrogen species and mechanism of the process. The hollow cathode discharge is also d

Plasma nitriding of a 3% Cr-Mo-V gear, a 310 SS PM slot, a 304 SS flat-disk, and an Inconel 718 fillet were performed to demonstrate the effects of reactive sputtering on case-depth uniformity. It was shown that the geometry of the sample in combinat

The goal of this paper is to demonstrate that glow discharge plasma heating of the cathode workpiece is different from radiant heating under vacuum, given the same pressure and gas composition, and that the final temperature obtained by the workpiece

The control of plasma nitriding relies on the ability to effect the transfer of nitrogen species into the cathode. Those species are either N+ ions implanted into the cathode or adsorbed nascent nitrogen atoms, coming from decomposed N2+ and NHx+ rad
