Recent progress in plasma nitriding
Vacuum, 2000Abstract The paper reports on a new system for plasma nitriding combined with a hollow cathode discharge sputtering at high pressures (about 1000 Pa), a new way of producing duplex coatings, and on a low-pressure (0.1–0.3 Pa) plasma nitriding using microwave discharges.

An in-situ study of plasma nitriding
Surface and Coatings Technology, 2007Abstract Direct in-situ observation of phase generation and growth during heat treatment cycles gives information independent e.g. of effects resulting from cooling and atmospheric changes of properties. In this investigation time resolved in-situ X-ray diffraction (XRD) analysis of growing nitride layers during plasma nitriding was conducted to gain

Abstract With the aim of optimizing the nitriding process, experimental studies of the plasma nitriding of four selected steels were carried out, using a d.c. glow discharge. The process parameters were varied systematically. By means of transmission and scanning electron microscopy and X-ray diffraction, the microstructures, including the ...

Abstract An intermetallic compound Sm 2 Fe 17 N x was synthesized by plasma nitriding of Sm 2 Fe 17 in a stream of N 2 H 2 mixed gas. The reaction proceeded at a lower temperature (around 423 K) than that of the conventional thermal technique, but not at room temperature.

Applied Surface Science, 1988
Abstract A new method of surface nitriding, called “plasma source nitriding”, has been developed. This method is different from “ion nitriding” in the following respects: (1) the function of nitrogen- and hydrogen-ion bombardment of a workpiece is independent of the function of plasma production, (2) a homogeneity of nitriding depth is obtainable ...

Abstract Martensite steel 0.5Cr12Ni2MoMgMn and titanium alloy TiMo1Zr4.5Sn3 were nitrided by high intensity nitrogen plasma bombardment (current densities were 3·1016 cm−2s−1 and 1.2·1017cm−2s−1 for martensite steel and titanium alloy correspondingly).

Low-temperature plasma-assisted nitriding
Surface and Coatings Technology, 2000 Plasma-assisted nitriding is an attractive surface treatment for metallurgical surface modification to improve wear, hardness and fatigue resistance of ferrous and non-ferrous materials. For this purpose, ion nitriding by a d.c.

Plasma Nitridation of Hydrogenated Silicon Nitride Film
Japanese Journal of Applied Physics, 2012In this study, chemical-vapor-deposited silicon nitride films were subjected to a novel nitridation process by use of self-biased nitrogen plasma. The film structure and electrical properties such as chemical bonding, surface morphology, dielectric strength, and the capacitance–voltage hysteresis of a metal–insulator–semiconductor device were ...

A Mössbauer study of plasma nitrided iron
Journal of Applied Physics, 1998Iron powder has been nitrided in a glow discharge plasma of a mixture of nitrogen and hydrogen, in order to verify the existence of a metastable iron nitrogen solid solution, previously observed from the Sm2Fe17N3 phase decomposition process. Our results show that, for short nitridation times, we obtain a mixture of Fe4N, a small amount of α-Fe and an ...
