Abstract:Surface layer hardness and concentration profiles of austenitic stainless steels after
plasma carburizing and /or nitriding at 673 K were investigated. Carbon and nitrogen concentration
were measured by glow discharge optical emission spectrometry (GDOES) and carbides or nitrides
were detected by x-ray diffraction analysis (XRD) and TEM. The state of carbon at the treated
surface was investigated by Raman spectroscopy. Separation of carburized layer and nitrided layer
was observed in a simultaneous carburizing… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
