摘要： Gas-driven permeation (GDP) and plasma-driven permeation (PDP) of hydrogen gas through GaInSn/Fe are systematically investigated in this work. The permeation parameters of hydrogen through GaInSn/Fe, including diffusivity, Sieverts' constant, permeability, and surface recombination coefficient are obtained. The permeation flux of hydrogen through GaInSn/Fe shows great dependence on external conditions such as temperature, hydrogen pressure, and thickness of liquid GaInSn. Furthermore, the hydrogen permeation behavior through GaInSn/Fe is well consistent with the multi-layer permeation theory. In PDP and GDP experiments, hydrogen through GaInSn/Fe satisfies the diffusion-limited regime. In addition, the permeation flux of PDP is greater than that of GDP. The increase of hydrogen plasma density hardly causes the hydrogen PDP flux to change within the test scope of this work, which is due to the dissolution saturation. These findings provide guidance for a comprehensive and systematic understanding of hydrogen isotope recycling, permeation, and retention in plasma-facing components under actual conditions.
