THE INFLUENCE OF LOW-TEMPERATURE PLASMA MODIFICATION WITH CARBON AND NITROGEN ON THE HARDENING AND SURFACE ROUGHNESS OF AUSTENITIC STAINLESS STEEL

Abstract

: Low-temperature plasma carburization and low-temperature plasma nitriding are the effective methods for hardening of thermally nonhardenable austenitic chromium-nickel steels. However, the ion-plasma methods of surface modification can lead to the roughness parameter increase. Previously, the authors identified that the level of surface roughness strongly depends on the temperature of plasma treatment. The hot topic of the research is the reduction of
