Low voltage hydrogen plasma interaction with palladium surface

Hydrogen penetration, distribution and content in palladium under low voltage glow discharge plasma, depending on plasma component structure (H₂, He, Ar and their mixtures), irradiation succession and possible surface structure changes have been investigated, using mass-spectrometry, SIMS, proton-proton scattering and electron microscopy techniques. Dependences of hydrogen permeability through palladium membranes upon the plasma component structure and the preliminary irradiation dose in the inert gas atmosphere have been revealed.
