PROCEDURE FOR THE SUPERFICIAL TREATMENT OF SINTERED PARTS, characterized in that sintered parts are heated in a vacuum, whose magnitude is so great that, for the moment, during the heating process itself no oxidation takes place, and because after arriving At the theoretical temperature under a certain partial pressure of O2 for a certain time, a uniform and superficial oxide layer is formed which protects the pieces against corrosion.
