Wetting Ability of Ag Based Molten Alloys on Graphite Substrate

摘要

The wetting angle (Θ) of molten Ag (Zn, Cu, Ga) drops on graphite substrate is investi-gated. 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-Cu alloy,and unexpected mixing between graphite substrate and the Ag-Ga melt was also detected in thesolidified structure.
