International Journal of Hydrogen Energy, 2008
Abstract The newly developed constant concentration method was adopted to study the hydrogen permeation of a hydrogen mixture of H 2 + Y through a palladium membrane tube. The hydrogen permeation of the hydrogen mixture differs from that of a single hydrogen feed. For the hydrogen mixture, the well-known Sieverts equation, Q = J

Hydrogen permeation through magnesium
Journal of Alloys and Compounds, 1999Abstract Hydrogen permeation characteristics have been investigated for pure magnesium membranes with a palladium overlayer using a gas permeation technique in the temperature range 473–493 K and in the hydrogen pressure range 0.1–10 kPa. For thicker specimens (thickness >2 mm), the permeation process was rate-controlled by the diffusion of hydrogen ...

The effect of permeation area ratio and shape on hydrogen permeation
Scripta Metallurgica et Materialia, 1994It is generally agreed that the factors influencing permeation and diffusion hydrogen at room temperature are as follows: the thickness and surface condition of the specimen, composition, microstructure and grain size of the material, hydrogen traps and stress or strain conditions for the specimen, etc.

Hydrogen permeation pathways for the hydrogenation reaction of aluminum
Journal of Applied Physics, 2010The hydrogenation of aluminum is inhibited by the slow diffusion of hydrogen in its hydride AlH3, which covers the surface of aluminum in the initial stages of the reaction. Thus, permeation pathways for hydrogen are introduced by either mixing aluminum powder with boron nitride powder or alloying aluminum with gallium at 10 at. % Ga.

The permeation of deuterium (D) from the gas phase into solution in iron has been measured using a new method based on ion beam analysis. For bare metal surfaces the D uptake was observed to be limited by matrix diffusion through the bulk. The influence of chemisorbed oxygen on the D uptake rate was examined in detail.

Hydrogen Permeation of Alloy 22
CORROSION 2008, 2008Abstract The effect of hydrogen permeation on the corrosion performance of Alloy 22 was investigated. 50µm thick Alloy 22 membranes were permeated with Hydrogen under a cathodic charging current density of 1mA/cm2 in a Devanathan-Stachurski cell at 60°C in pH 12.5, 0.1M NaOH solution.
