Formation and kinetics of aluminide coating on 316L stainless steel by pack cementation process
He jishu, 2023 BackgroundPack cementation aluminizing technology is a common method for preparing tritium barrier coatings, and its relative parameters during the preparation process have an important influence on the microstructure of the aluminide layer and the ...

Stone–Wales Defect in Graphene
Small, Volume 19, Issue 44, November 1, 2023., 2023 Defects in graphene may be attributed to intrinsic or extrinsic reasons, but they often deteriorate the uniqueness and confine their applications in devices. This article discusses Stone–Wales (SW) defect in graphene and its derivatives comprehensively.

Deuterium permeability of a novel AlCrTaTiZr high entropy alloy coating
Materials Research Express, 2021 AlCrTaTiZr, AlCrTaTiZr nitride, and AlCrTaTiZr oxide coatings as tritium permeation barriers (TPBs) were prepared by magnetron co-sputtering technology on a CLF-1 (RAFM) substrate, to evaluate their hydrogen/deuterium permeation resistance.

THIN NITRIDE LAYERS AS PERMEATION BARRIERS
Acta Polytechnica CTU Proceedings, 2018 Permeation barriers represent one of the crucial fields in materials development for thermonuclear fusion. Primary objective of the barriers is to suppress the permeation of hydrogen isotopes (mainly tritium) from future thermonuclear fusion facilities ...

Study on the in-situ oxidation process of aluminizing layer formed on GH3535 superalloy
He jishu, 2023 BackgroundUnder high-temperature operating conditions, the tritium would be generated inside the core of thorium-based molten salt reactor (TMSR) and probably diffuse through the structural material into the environment.

Solubility and diffusivity of hydrogen and its isotopes in the BeO system
Journal of the American Ceramic Society, Volume 106, Issue 8, Page 5005-5021, August 2023., 2023 Abstract This work revisits hydrogen insertion in the wurtzite beryllium oxide in order to fill the gap in scientific knowledge regarding the diffusion coefficients of the different chemical states of hydrogen (neutral, charged, or molecular). Both first‐principle and macroscopic models were used to this end.
