The effect of Me-Ti inter-atomic interactions on wetting in CaF2/(Me-Ti) systems: Ab-initio considerations
چکیده انگلیسی
For the system with stronger inter-atomic attraction in the melt (Sn-Ti alloys), Ti atoms prefer to be surrounded by Sn atoms, and only weakly affect the metal/substrate interfacial energy and, thus the observed contact angle. However, for weak inter-atomic attraction (In-Ti alloys) an enhanced Ti adsorption at the metal/substrate interface takes place and leads to decrease the interfacial energy and improved wetting. The differences in the wetting behavior for these systems are discussed in terms of the total energy of each system, the electron charge re-distribution and the electron Density of States.
