Hydrogen permeation through tritium permeation barrier in Pb–17Li

Fusion Engineering and Design, 2001
One of the main problems in the development of water cooled lithium lead (WCLL) DEMO fusion reactor is the reduction of the tritium permeation from the Pb–17Li, or the plasma, into the cooling water. The control of tritium losses is an important issue in fusion technology because of its safety and operational implications.

Hydrogen permeation behavior of X70 pipeline steel simultaneously affected by tensile stress and sulfate-reducing bacteria

International journal of hydrogen energy, 2019
The hydrogen permeation behavior of submarine pipelines buried in anoxic sea mud and protected by cathodic potential is affected by both sulfate-reducing bacteria (SRB) and tensile stress. In this study, the individual and simultaneous effects of SRB and

Analysis of hydrogen permeation tests considering two different modelling approaches for grain boundary trapping in iron

International Journal of Fracture, 2019
The electrochemical permeation test is one of the most used methods for characterising hydrogen diffusion in metals. The flux of hydrogen atoms registered in the oxidation cell might be fitted to obtain apparent diffusivities.

Hydrogen permeation through steels during phosphatizing—II. Effect of phosphate coatings on hydrogen permeation

Corrosion Science, 1971
Abstract Hydrogen permeation through steel during phosphatizing in accelerated and non-accelerated solutions has been investigated using a modified Devanathan cell. It has been established that in an accelerated solution hydrogen permeation is less than in an unaccelerated solution, which is thought to be due to the higher interfacial pH and greater ...

Preparation of Cr2O3/Al2O3 bipolar oxides as hydrogen permeation barriers by selective oxide removal on SS and atomic layer deposition

International journal of hydrogen energy, 2019
Iron-nickel based stainless steel (SS) applied in nuclear plants as a substrate material barely suppresses the permeation of hydrogen plasmas, which are mainly composed of positive and negative hydrogen ions with trace amounts of non-ionized hydrogen ...

Impact of vacuum operation on hydrogen permeation through a palladium membrane tube

International journal of hydrogen energy, 2019
Palladium (Pd) membranes are characterized by their high permselectivity to hydrogen and easy operation, and are promising devises for separating hydrogen from hydrogen-rich gases.

Hydrogen permeation and diffusionin Fe−Ti alloys

Journal of the Less Common Metals, 1991
Abstract Repetitive electrochemical permeation measurements have been combined with the oscillating gas permeation method to investigate the effect of titanium in ferrite on hydrogen trapping. The specimens used were pure iron and FeTi alloys with 0.233, 0.641, 0.99 and 1.80 at.% Ti.

Slow strain rate tests coupled with hydrogen permeation: New possibilities to assess the role of hydrogen in stress corrosion cracking tests part I: Methodology and commissioning results

Corrosion Science, 2019
Slow Strain Rate Tests (SSRT) is a methodology to assess the influence of hydrogen in stress corrosion cracking. However, additional information correlating SSRT and hydrogen permeation might provide a better understanding of the influence of hydrogen on
