To suppress this, tritium permeation barriers are developed. Suitable materials for the permeation barriers are those with low hydrogen isotope permeability - primarily ceramic materials, such as oxides, carbides and nitrides. In this study, coatings of six less common nitrides prepared by physical vapor deposition – namely AlCrN, CrN, Cr2N, CrWN, WN and ZrN – were investigated. Besides basic characterization (elemental and phase composition, surface morphology and coating thickness), hydrogen permeation, adhesion, residual stress and thermal expansion were evaluated. All coatings were dense, crack-free and well adherent. The permeation reduction factor which was determined at 400 °C and 1 bar ranged from ˜102 to ˜5 × 103, the best performance being achieved by the ZrN coating. As these materials seem not to be investigated as hydrogen permeation barriers, they have a very high potential to be further improved Pracoviště Ústav fyziky plazmatu Kontakt Vladimíra Kebza, kebza@ipp.cas.cz, Tel.: 266 052 975 Rok sběru 2020 Elektronická adresa https://www.sciencedirect.com/science/article/pii/S0920379618308214?via%3Dihub
