摘要
Hydride-forming alloys with highly reactive surfaces have been developed by treating with a fluorine-containing aqueous solution. They exhibit excellent reactivity for hydrogen uptake. The surface properties of the fluorine-treated LaNi4.7Al0.3 alloy were studied by X-ray photoelectron spectroscopy and secondary ion mass spectroscopy. Surface compositions were analysed and compared with that of the untreated sample. After fluorine treatment, fine net-like crystallites of less than 1 mum are formed and segregation of the alloy components takes place on the surface.
