进行了氘等离子体驱动渗透（PDP）实验，通过减少激活铁素体/马氏体（RAFM）钢与无钨（W）沉积层。结果表明，W沉积并不总是作为D渗透阻挡层，但在一定条件下提高D渗透通量通过结构材料。在稳态下，PDP通过具有薄（~30 nm）W沉积层的RAFM钢的通量大于裸RAFM钢的通量，而具有厚（6.0 μm）W沉积层的RAFM钢膜的渗透通量低于裸钢样品的通量。氚迁移分析程序（TMAP）的计算表明，稳态渗透通量取决于W层与RAFM钢界面处累积的氚浓度，且与W层厚度密切相关。只有当W厚度大于~2 μm时，稳态渗透通量才由W沉积层中的扩散控制。
Deuterium (D) plasma-driven permeation (PDP) experiments through reduced activation ferritic/martensitic (RAFM) steel with and without tungsten (W) deposition layer have been performed. The results confirm that W deposition does not always work as D permeation barrier, but enhances D permeation flux through the structural material under certain conditions. The steady state PDP fluxes through RAFM steel with a thin (~30 nm) W deposition layer have been found to be larger than those of bare RAFM steel, whereas the RAFM steel membrane with a thick (6.0 μm) W deposition layer exhibits lower permeation fluxes than those of bare steel sample. Tritium Migration Analysis Program (TMAP) calculation indicates that the steady state permeation flux is determined by the D concentration accumulated at the interface between W layer and RAFM steel, which is highly relevant to the W deposition thickness. Only when the W thickness is larger than ~2 μm, the steady state permeation flux will be controlled by diffusion in W deposition layer.
