抄録

Hydriding characteristics of LaNi4.7Al0.3 alloys with surfaces modified by high-purity anhydrous HF were evaluated after long-term preservation in air. Affected by poisoning species in air, untreated alloy hydriding activity was enormously decreased. HF-treated alloys with a modified surface layer containing metal fluoride NiF2, LaF3 and AlF3 maintained relatively high activity. In high-humidity air, metal fluoride NiF2 reacted with moisture to form hydrous Ni(OH)2, and permeation of poisonous species such as O2, CO and CO2 was markedly inhibited by moisture-condensed hydrate screens.
