Con\u00e7us pour \u00e9tablir une liaison m\u00e9tallurgique stable, les cylindres en fonte \u00e0 haute teneur en chrome de DURON (S\u00e9rie HCr) sont coul\u00e9s par centrifugation. La structure se caract\u00e9rise par une matrice dense satur\u00e9e de carbures d’alliage eutectiques M7C3, offrant une r\u00e9sistance \u00e9lev\u00e9e \u00e0 l’usure et une r\u00e9sistance stable \u00e0 l’oxydation de surface. Nous contr\u00f4lons les param\u00e8tres d’alliage pr\u00e9cis, y compris des ajouts r\u00e9gul\u00e9s de vanadium (V), pour garantir une profondeur de couche utile et une stabilit\u00e9 thermique constantes. Les compositions chimiques et les sp\u00e9cifications m\u00e9tallurgiques de ces cylindres en fonte \u00e0 haute teneur en chrome sont d\u00e9taill\u00e9es ci-dessous : <\/p>\n\n
