摘要

Magnesium films prepared by vacuum evaporation were implanted with vanadium and palladium ions in order to study their hydrogenation characteristics. It was found that the hydrogenation kinetics depend on the ion species and on the ion dose implanted. Indeed, the vanadium-implanted magnesium films have faster kinetics than the palladium-implanted ones. However, low vanadium concentration (approx 0.3 at. percent) seems to inhibit the absorption reaction. Among the ion-implanted magnesium films, the fastest kinetics were obtained with the vanadium-implanted film at a dose of 1 X 10~(16) ions/cm~2: at 623 K and under a hydrogen pressure of 10 bar, a concentration of 6 wt. percent of hydrogen was reached in 270 min during the first hydrogenation and in 45 min during the second one.
