摘要

New procedure to increase the wear resistance due to friction as well as abrasion and fatigue without deformation of the ferrous alloys; characterized in that the parts to be treated after having undergone a previous immersion in a normal sulfinization bath are subjected to rapid heating by means of a high frequency electric field.
