Research of hydrogen saturation of magnesium and magnesium-aluminum films and the influence of a protective nickel coating on it

Abstract

Experiments on the hydrogenation of Mg-Al films during their deposition by magnetron sputtering in a hydrogen atmosphere and subsequent gas-phase hydrogenation have been carried out. The hydrogen mass content and the rate of hydrogen desorption from the obtained metal hydride films have been determined. The key effect of the nickel protective coating on Mg-Al films for their use in hydrogen film accumulators is shown.
