Horizontally aligned BN nanosheet array for nanometer-thick ZrO2 coating with greatly enhanced anticorrosion and hydrogen isotope resistance property

Thermochemically synthesized α‐Al2O3 composite coating with high bonding strength and deuterium permeation resistance

“…It is worthy to note that only one face of the steel substrate was coated with α-Al 2 O 3 . In our homemade gas-driven deuterium permeation device, 31,32 the upstream and downstream chambers are separated by the sample. Deuterium gas is introduced into the upstream chamber when the vacuum of the two chambers drops below 10 −4 Pa. Once deuterium atoms penetrate through the sample and enter into the downstream chamber, their ion current is tracked timely by a quadrupole mass spectrometer (QMS) equipped.…”

Controlled local orientation of 2D nanomaterials in 3D devices: methods and prospects for multifunctional designs and enhanced performance

“…A heterogeneous film with a multilayer structure can be formed by repeating the dipping process. 320 The formation of a layered structure with high ordering is closely related to the strong interactions between individual components, such as electrostatic force, covalent bonding, hydrophobic interaction and so on. 129,213 To guarantee high LBL packing, the deposited material components should be selected to bound together.…”

Effect of Cr2O3 nanosheet insertion on the deuterium permeation behavior of a Cr-Zr-O coating

“…The permeation reduction factor (PRF) and permeation flux are two important indexes that are used to measure the performance of a deuterium permeation barrier. The self-constructed gasdriven deuterium permeation test device was depicted in our previous work [22][23][24][25][26], which is separated by the sample into upstream and downstream cavities. A dynamic vacuum (10 −5 Pa) is kept in the upstream and downstream cavities by two molecular pumps.…”
