VERFAHREN ZUR BEHANDLUNG VON TEILEN AUS EISENLEGIERUNG ZUR VERBESSERUNG DER REIBEIGENSCHAFTEN OHNE VERURSACHUNG VON HÄRTEVERLUST ODER VERFORMUNG

摘要

A method for obtaining a ferrous alloy part that supports a very high seizure load with very low dispersion includes steps of covering the part with an iron sulphide coating having an appropriate thickness and Fe/S ratio, where the coating is selected from among those with surfaces having a fractal dimension that is at least equal to 2.6.
