Study of hydrogen storage capacity of Ti induced by ion irradiation

A study of the change in hydrogen absorption of titanium due to ion irradiation is presented. Titanium slices were irradiated at room temperature with 700 and 1500 keV H ions and annealed at 300, 450 and 600 °C in a hydrogen atmosphere in order to study the absorption of hydrogen into the material. ERDA measurements and X-ray diffraction analysis show an improvement in hydrogen absorption relative to those samples that were not irradiated previously to hydrogenation. A tendency of an increment of the surface hydrogen storage density with diminishing the irradiation energy was also observed.
