Salt bath nitrocarburizing at temperatures outside the conventional temperature range can offer improved performance in mechanical properties for plain carbon, alloy and austenitic stainless steels, as well as some cost benefits.
Historically, the processing temperatures used for ferritic nitrocarburizing in molten salt baths have been in the range of 1000 to 1075[degrees]F (540 to 580[degrees]C). This is based on kinetics and thermodynamics of the reactions required to produce particular nitride phases, which, in turn, develop the desired engineering properties. Recent work is directed toward nitrocarburizing at temperatures outside the normal range using plasma ...
