Results in Hungarian
A 4-éves projekt célja határfelületi energiák, erők és jelenségek vizsgálata volt fémolvadék fázist tartalmazó rendszerekben, melynek keretein belül részben kísérleti, részben elméleti munkát végeztünk. A munka eredményeiből 17 impakt faktoros folyóiratcikk jelent meg, melyekre a mai napig 42 független hivatkozást kaptunk. A kísérleti munka során a. sóolvadékban vizsgáltuk kerámiaszemcsék fém titánnal való felületi bevonásának lehetőségét, b. fémolvadékok felületi feszültségét és peremszögét mértük kerámiákon, c. felületi fémmátrixú kompozitot állítottunk elő lézeres felületkezeléssel. A projekt keretein belül kidolgozott elméleti modellek típusai: a. határfelületi (és innen származtatott) anyagtulajdonságok modellezése: fémolvadékok felületi feszültsége, kohéziós energiája, viszkozitása, egyéb határfelületi energiák, ezek koncentrációfüggése, különös tekintettel a felületi fázisátalakulásra, b. határfelületi erők modellezése: közös, általános képlet és algoritmus megalkotása - egyszerűsített geometriákra a hat, különböző határfelületi erő képletének levezetése, c. komplex határfelületi jelenségek modellezése, úgymint kristályfront – kerámiaszemcse kölcsönhatás, szemcse – fémolvadékfelület dinamikai kölcsönhatása, fémolvadék infiltráció különböző morfológiájú preformákba, szemcsékkel erősített fémmátrixú kompozitok, illetve szemcsékkel stabilizált fémhabok és fémemulziók stabilitása.
Results in English
The goal of the 4-year project was to study interfacial energies, forces and phenomena in systems, containing a liquid metallic phase. 17 papers in journal with impact factors have been published, with total 42 independent references obtained so far. Experimentally the following subjects were covered: i. the possibility to coat ceramic particles by metallic titanium from molten salt was investigated, ii. surface tension of liquid metals and their contact angle on ceramic plates were measured, iii. a surface composite material was produced by a Laser Melt Injection technique. Theoretically the following types of models were developed: i. modeling interfacial (and related) properties, such as surface tension, other interfacial energies, cohesion energy and viscosity of liquid metals, their concentration dependence, with emphasis on surface phase transition, ii. modeling interfacial forces – the derivation of a most general equation and algorithm top derive interfacial forces, and the derivation of equation (for simplified geometries) for the 6 types of interfacial forces, iii. modeling complex interfacial phenomena, including the interaction of a solidification from with particles, dynamic interaction of particles with liquid surfaces, infiltration of liquid metals into preforms of different morphologies, stability of particle reinforced metal matrix composites, particles stabilized metallic foams and emulsions.
