Abstract:
A mechanism of diffusion, solubility and permeability of hydrogen through amorphous alloys (Fe- and Pd-based alloys) is investigated by the computer simulation method with the use of molecular dynamic models. It is ascertained experimentally that the permeable hydrogen flow shows the Arrhenius temperature dependence for recrystallized specimen and nonmonotonous temperature dependence for amorphous specimen. A model of hydrogen permeation is suggested that takes into account the features of reemission and diffusion in contact with glow discharge. The appropriate kinetic and energetic parameters are evaluated.
