“…As discussed above, diffusion-controlled permeation through metals is proportional to the square root of the hydrogen partial pressure. Perujo, et al [214] reported that the pressure dependence of permeation through MANET plasma sprayed with aluminum changed from the classic square root dependence to linear as the pressure was decreased below 20,000 Pa. McGuire [215] also noted the transition to near linear pressure dependence in the pressure range from 200 to 1000 Pa. Linear pressure dependence is symptomatic of permeation limited by absorption or recombination.…”

Tritium and deuterium induce radiation in reactor materials and some radioactive tritium gas may be released. Most of the materials used in fusion reactors are metals that have relatively high permeabilities for tritium. The fusion community has been working on barriers to minimize tritium release. Unfortunately, most barrier materials work very well during laboratory experiments, but fail to meet requirements when placed in radiation environments.This chapter presents tritium permeation characteristics of various materials used in fusion reactors, including plasma-facing, structural, and barrier materials. The necessary parameters for tritium release calculations for various regions of a fusion reactor are given.

“…Новые технологии в области металлургии не могут обеспечить полную защиту от проникновения водорода вглубь материала. Поэтому для целей защиты конструкционных и функциональных материалов от водородного охрупчивания остается актуальной разработка технологий создания тонкопленочных покрытий [1][2][3][4][5][6][7][8]. Свойства пленки оксида алюминия (Al 2 O 3 ) были исследованы на сталях и цирконии.…”

In this study, we have considered interaction between an aluminum oxide film magnetron-sputtered on commercially pure VT1-0 titanium and a hydrogen atmosphere. The time the system was exposed to hydrogen varied from 1 to 4 h with all other parameters remaining the same. Data for the distribution of hydrogen over the depth (film thickness) and its content in the thin-film system have been obtained, and the influence of the hold time in hydrogen on the adhesion and friction coefficient of the film has been revealed. In addition, the surface conductivity and hydrogen distribution in the aluminum oxide film have been determined.

“…Therefore, development of tritium permeation reduction coating has been carried out extensively. Ceramic coating materials such as Al 2 O 3 [3][4][5] and TiN/TiC [6] have been studied in fabrication experiments and property measurements. Al 2 O 3 coating has been developed using vacuum plasma spraying and pack-cementation methods, and TiN/TiC coating has been developed using chemical vapor deposition methods.…”
