Description	Nitriding has long been employed to harden the surfaces of austenitic stainless steels. However, conventional nitriding at temperatures above 500°C normally results in a significant reduction in the corrosion resistance of the material, due to the formation of chromium nitride precipitates in the nitrided case. Attempts have been made to tackle this problem mainly by lowering the nitriding temperature. It has been established that when the nitriding temperature is sufficiently low, precipitation of chromium nitrides can be suppressed and a hard and corrosion resistant layer can thus be produced on austenitic stainless steels, achieving combined improvement in wear and corrosion resistance. More recently, it has been discovered that carbon can also be used as the major alloying species to engineer the surfaces of austenitic stainless steels. This has led to the development of a low temperature plasma carburising process for these materials to achieve not only combined improvement in wear and corrosion resistance, but also enhanced load bearing capacity and toughness. The present paper discusses various aspects of both the low temperature plasma nitriding and carburising processes, in terms of process characteristics, structural evolution, layer growth kinetics, mechanical and chemical properties evaluation.
