Abstract

Procédé d'obtention d'une pièce en allige ferreux supportant une charge de grippage très élevée avec une dispersion très faible, consistant à déposer sur ladite pièce un revêtement de sulfure de fer ayant une épaisseur et un rapport Fe/S appropriés, caractérisé en ce que l'on sélectionne le revêtement parmi ceux dont la surface a une dimension fractale au moins égale à 2,6. Pièces obtenues selon ce procédé.
