The Influence of Desorption Kinetics on Hydrogen Permeation in Iron.

Abstract

The common observation that the diffusivity of hydrogen in iron decreases anomalously at low temperatures is treated in terms of the barrier to atom recombination and desorption that is known to be associated with the surfaces of this metal. Results obtained are in good agreement with both data on deuterium permeation through a polycrystalline iron sample, obtained in this study, and with the body of measurements for hydrogen diffusion through iron found in the literature.
