Abstract

Improvements introduced in the object of the main patent no. 395.042 requested on september 13, 1971 by "procedure for the hardening of surface in two stages of workpieces made with hardened iron or steel alloys", characterized in that for the increase of the concentration of the energy in the treatment with plasma, the workpieces are arranged in an electrically insulating liquid in such a way that the surface area to be treated is covered before treatment with a liquid layer of uniform thickness, which is displaced by the flame of the plasma from the surface area of the workpiece covered in each case by the treatment.
