Plasma-assisted nitriding is an attractive surface treatment for metallurgical surface
modification to improve wear, hardness and fatigue resistance of ferrous and non-ferrous …

Over the last 40 years, the commercial production of titanium and its alloys has increased
steadily. Whilst these materials have some very attractive properties, enabling applications …

This paper attempts to reduce some of the confusion that exists over the nature of the
nitrogen-rich layer produced by nitriding austenitic stainless steel at temperatures below …

Martensitic grade stainless steel AISI 420 was nitrided in a low-pressure RF plasma using
pure nitrogen. With a treatment time of 4.0 h at 400° C, the nitrogen-rich layer on the sample …

Plasma nitriding of austenitic stainless steel samples has been carried out using pulse dc
glow discharge plasma of NH3 gas at substrate temperature ranging from 350 to 520° C. A …

As we previously confirmed, the m phase, forming as a single-phase layer upon ion nitriding
of AISI 316L stainless steel under mild conditions, has a centered tetragonal structure with …

Model experiments with low-energy ions under controlled vacuum conditions have been
performed in order to identify the surface processes and diffusion mechanism associated …

The influence of treatment pressure on the characteristics of the modified surface layers
produced by low-temperature dc glow discharge nitriding on AISI 316L austenitic stainless …

A model for the transport of nitrogen in austenitic stainless steel at temperatures around
400° C is presented and discussed. The model considers the diffusion of nitrogen under the …

AISI 316 L austenitic stainless steels (316 L SS) were nitrided to enhance their mechanical
property and corrosion resistance by a high efficiency low-pressure arc plasma nitriding …
