“…In the case of ion-covalent-bonded substances such as ceramics, the hydrogen dispersion in iron and steel is known to be several orders of magnitude less [1,18,19]. As regards iron nitride or a nitrogen-dispersed phase in the current study, the present paper does not give a full account of how or where the atomic hydrogen is dispersed and trapped; this is a topic for further research.…”

Abstract:The surface of austenitic stainless steel SUS316L was treated with nitrogen-plasma and its hydrogen permeability function was investigated. On the stainless steel surface, a nitride phase and a nitrogen-dispersed phase were found 5 m from the surface. The nitride phase was mainly consisting of -Fe 2-3 N particles 0.1-0.4 m in size. This nitride phase had hydrogen permeability an order of magnitude less than that for the untreated sample. The plasma nitride sample was confirmed to have a hydrogen permeation prevention effect.

“…For example, films such as Al 2 O 3 , TiN, TiC, and BN are efficient hydrogen barriers [1][2][3]. Films created using methods such as PVD show better adhesion with the metal surface, have fewer inner vacancies or particles, and are known to be suitable for fine and smooth surfaces.…”

“…Hollenberg et al [36] provides an excellent overview of several permeation studies performed with aluminized materials, including those listed above, and provides some additional insights into the permeation mechanisms in these materials, and reiterates that the resistance to hydrogen permeation is related to the presence of surface defects in the coating. At lower pressures, a surface-limiting phenomenon may control the permeation rate, and the exponent on Equation 8 will tend towards a value of 1.…”

“…Since candidate structural structure materials generally exhibit high permeability of hydrogen isotopes in the operational temperature range, it is essential to suppress tritium permeation through pipe walls. For many years, ceramic coatings have developed as one method of reducing tritium permeation [1,2].…”

Hydrogen isotope concentrations in erbium oxide coatings fabricated by filtered arc deposition and metalorganic decomposition have been investigated using nuclear reaction analysis and secondary ion mass spectroscopy. It was found that deuterium concentration in the coatings fabricated by filtered arc deposition was 300-500 atomic parts per million, whereas the deuterium concentration in the coating fabricated by metal-organic decomposition was approximately 2.0 × 10 4 atomic parts per million due to hydrogen trapping by carbon impurities. Deuterium concentrations in the coatings by filtered arc deposition increased with increasing depth in accordance with the increase of grain boundary area density. An in-plane deuterium distribution of the coating by secondary ion mass spectroscopy proved the segregation with a net-like structure, indicating that the deuterium diffused through the grain boundaries.
