Abstract (en)
[origin: US7172794B2] 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.
