Abstract
The wettabilities of carbon-saturated Fe-Cu, Fe-Sn and Fe-S melts to graphite were measured by the sessile drop method. The works of adhesion of those alloys with graphite are dependent upon the solubility of carbon in those alloys. With an increase in the content of the above alloying elements in liquid alloys, the solubility of carbon and the work of adhesion decrease. This is why the surface-active elements, Cu, Sn and S, are considered to segregate at the interface between the liquid alloys and the graphite as well as at the surface of the liquid alloys. Those segregation phenomena may interfere the wettability of the liquid alloys to the graphite.
