“…Our studies have demonstrated for the first time the possibility of production of rapidly solidified (RS) aluminum alloys with controlled wettability to protect materials from the harmful effects of water. Earlier we revealed that nature of water wetting of both foil surfaces of pure Al received by high-speed crystallization from melt is hydrophobic [3][4][5]. Addition of low-melting In additive to Al, which forms monotectic system with aluminum, significantly changes the nature of water wettability of foil surfaces.…”

The microstructure, elemental and phase composition of rapidly solidified foils of Al-In alloys were investigated using SEM with EDX, XRD and RBS. It was found that thin surface layers of foils are enriched with indium that results in hydrophilization of alloys. Wetting transition from the homogeneous Wenzel state to the heterogeneous Cassie-Baxter state observed when indium content increases at the foil surface of hydrophilic Al-In alloys is discussed in terms of the penetration of water into the micro/nanostructures of foil surfaces. Streszczenie. Na podstawie pomiarów SEM z EDX, XRD i RBS przeprowadzono badania składu pierwiastkowego, fazy i mikrostruktury szybko zestalonych powłok stopów Al-In. Stwierdzono, że cienkie warstwy powierzchniowe powłok wzbogacają się w ind, co powoduje hydrofilizację stopów. Przejście zawilgocenia z jednolitego stanu Wenzel do heterogenicznego stanu Cassie-Baxter, obserwowanego gdy następuje wzrost zawartości indu na powierzchni powłoki hydrofilowych stopów Al-In, zostało przeanalizowane pod kątem wnikania wody do powierzchniowych mikro i nano struktur powłoki.
