We study the accumulation of deuterium in coatings made of FeCrAl alloys and stainless steel, as well as (for comparison) in the Zr1%Nb alloy under the conditions of their saturation with a hydrogen isotope (deuterium) from a gaseous medium. By the method of nuclear reactions, we measure the space distribution of the concentration of deuterium in the coatings after their saturation at a temperature of 450°C (PD = 2·10–3 Pa for 120 min). It is shown that, for the investigated temperature and pressure, deuterium does not penetrate into the bulk of the coatings and is adsorbed in their subsurface regions from which it is then desorbed at a heating temperature higher than the room temperature by 20–30°С.

铁基真空电弧涂层的氘饱和特性

我们研究了在由气态介质中的氢同位素（氘）饱和的条件下，氘在由 FeCrAl 合金和不锈钢制成的涂层中的积累，以及（作为比较）在 Zr1%Nb 合金中的积累。通过核反应的方法，我们测量了涂层在 450°C（PD = 2·10-3 Pa，持续 120 分钟）下饱和后氘浓度的空间分布。结果表明，对于所研究的温度和压力，氘不会渗透到大部分涂层中，而是被吸附在其次表面区域，然后在比室温高 20-30°С的加热温度下解吸.
