Surface modification of austenitic stainless steel by high current ion
nitriding at 400 degrees C has been studied by Slow Positron Implanta
tion Spectroscopy (SPIS). In addition, Nuclear Reaction Analysis (NRA)
has been applied to obtain information about the nitrogen depth profi
le. The results obtained from both methods are compared and discussed
with respect to the nature of defects produced by high current ion nit
riding and their influence on the formation of a surface layer, called
expanded austenite. (C) 1998 Elsevier Science B.V.
