Abstract

The penetration of hydrogen through protective layers of aluminum oxide fixed on the surface of nanocrystalline (NC) titanium is studied. A film 400 nm thick is prepared by the magnetron sputtering. Radiation- and thermally-induced gas release are employed. It is found that the Al _x O_1-x film prevents the release of hydrogen from a sample under both radiation and thermal effects. The temperature of hydrogen extraction from metal hydride accumulators can be reduced by 200-250°C, provided that heating is performed under conditions of surface irradiation by electrons with energies of ∼30 keV and current densities of 2 to 3 μA cm^-2.
