预期氚渗透屏障（TPB）的准确氚传输特性对于聚变反应堆中的氚系统至关重要。通过将温度和速率控制的吹扫气体吹过样品表面，将渗透的氚带到电离室，在带有Al2O3/FeAl屏障的321型不锈钢容器上进行气体驱动的氚渗透，以确定屏障的抗T渗透性能和机理。 Al2O3/FeAl涂层容器在500~700°C时的氚渗透率比裸容器降低了3个数量级，满足CN-HCCB TBM氚工作部件TPB氚渗透降低因子（PRF）的要求。 Al2O3/FeAl阻挡层通过在块状衬底中有限数量的缺陷位点上的扩散来抵抗氚渗透，这表明TPB质量是有效抵抗氚渗透的一个非常重要的因素。
Accurate tritium transport properties of prospective tritium permeation barriers (TPBs) are essential to tritium systems in fusion reactors. By passing a temperature and rate-controlled sweeping gas over specimen surfaces to carry the permeated tritium to an ion chamber, the gas-driven permeation of tritium has been performed on 321 type stainless steel containers with Al2O3/FeAl barriers, to determine the T-permeation resistant performance and mechanism of the barrier. The tritium permeability of the Al2O3/FeAl coated container was reduced by 3 orders of magnitude at 500–700 °C by contrast with that of the bare one, which meets the requirement of the tritium permeation reduction factor (PRF) of TPBs for tritium operating components in the CN-HCCB TBM. The Al2O3/FeAl barrier resists the tritium permeation by the diffusion in the bulk substrate at a limited number of defect sites with an effective area and thickness, suggesting that the TPB quality is a very important factor for efficient T-permeation resistance.
