Thin Pd films are used as protective layers against reoxidation of cleaned less noble metals in order to allow an easy hydrogen uptake. The hydrogen permeability through the Pd‐films into the substrate metal depends strongly on the film preparation conditions especially on the deposition rate and substrate temperature during deposition. Various measurements (including resistivity, electrochemical diffusion, SIMS and AES, gravimetrical and X‐ray diffraction measuring techniques) have been applied to characterize film samples prepared in different ways in order to find the optimal conditions to prepare protective but hydrogen permeable Pd‐films. It could be shown that the hydrogen uptake from the gas phase is mainly determined by adsorption layers on the film surface, additionally the hydrogen permeability is closely connected with the structure of the interface between film and substrate. Low deposition rates and increased substrate temperatures during preparation are the basis to obtain Pd‐films with best properties for an easy hydrogen uptake and permeability. |
