文章叙述了氚在305铝合金及其预生膜中渗透率的测量方法,推导出计算氚在305铝合金及其预生膜中的渗透率的经验公式。实验结果表明氚在镀预生膜的铝中的渗透率低,在100-250℃铝表面镀层阻挡氚渗透效果极为明显,而且温度越高效果越显著。
The article describes the measurement of the permeability of tritium in 305 aluminum alloy and its pre-formed film, and deduces the empirical formula for calculating the permeability of tritium in 305 aluminum alloy and its pre-formed film. The experimental results show that the permeability of tritium in pre-coated aluminum is low, and the effect of tritium permeation is very obvious at the temperature of 100-250 ℃. The higher the temperature is, the more obvious the effect is.
