The temperature dependence of wetting angles (T) of Ag-M based melts (M: Cu, Zn, Ga) on graphite substrates are compared. The slope of (T) is negative, which follows from the Eötvös rule. The difference in the slope arises from the M alloying elements. A texture formation was found in the substrate/drop interphase region after solidification. The enrichment (segregation) of Ag atoms in the interface layer was observed in the Ag-Ga alloy in the solidified structure. The action of the melt temperature was examined also on the degree of texture formation, which seems to be coupled with the magnitude of the contact angle.
