Hydrogen permeation barriers and preparation techniques: A review

Journal of Vacuum Science & Technology A, 2022
In the hydrogen energy industry, penetration of hydrogen into storage and transportation materials is a big problem because the process causes cracks, equipment damage, hydrogen leakage, failure, and even explosion. Hydrogen permeation barriers are, thus,

Hydrogen permeation and distribution at a high-strength X80 steel weld under stressing conditions and the implication on pipeline failure

, 2021
Hydrogen permeation and distribution at pipeline welds is critical to integrity maintenance of the pipelines, especially for those made of high-strength steels. The situation becomes even more important under stressing conditions.

Influence of iron oxides and calcareous deposits on the hydrogen permeation rate in X65 steel in a simulated groundwater

, 2021
The hydrogen permeation behavior of X65 steel was studied in a simulated Canadian groundwater (NS4) using a Devanathan-Stachurski cell. In the absence of a palladium coating on the detection side of the steel membrane, the hydrogen permeation current was

The effect of permeation area ratio and shape on hydrogen permeation

Scripta Metallurgica et Materialia, 1994
It 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, 2010
The 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.
