The article is discussing the issue of the graphite degradation emission in the surface layer of a nodular iron casting. A diffusion of sulphur from moulding sand to the surface of the casting is a cause of this occurrence. Examinations present the influence of the quality of the reclamation sand of furan no-bake sand to the arrangement and the size of the degenerate graphite zone.
