Abstract

Procedure for the two-stage surface hardening of workpieces made with hardenable iron and steel alloys, characterized in that for the production of surface areas of killstable austenite with permanent cross-sectional shapes and permanent properties, they are provided to the part during the treatment of amounts of energy of equal magnitude in the unit of time, with cold plasma, through which a high-frequency current circuit with constant frequency is galvanically closed.
