On Enhancing the Thermal Stability of Metal Hydrides by Ion–Plasma Vacuum Magnetron Sputtering

Abstract

The method of titanium-hydride pellet (THP) modification by the surface deposition of metal titanium with the ion–plasma vacuum magnetron sputtering is described in this paper. The surface microstructure of the initial samples is compared with that of samples with the deposited coating. Found to be practically the same along the surface, the thickness of the deposited layer equals approximately 275 nm. The interface between the deposited titanium and THP is visible over the entire recorded region. The spectra of the thermal desorption of hydrogen from the initial and titanium-coated samples are presented. The coating is shown to significantly increase the temperature of THP dissociation.
