研究了673 K下氧化过程中SS-316中氘滞留的离子注量依赖性,以评估SS-316氧化层中氘滞留的动力学。用XPS和TDS研究了不锈钢的化学状态与氘滞留量之间的关系。结果表明,氘的主要解吸温度在660 K和935 K附近,这与氢氧化物形式的氘的解吸相对应。氘保留率随着氘离子注量的增加而增加,因为氢氧化物形式的氘保留率显著增加。然而,保留在离子注量为102.5 × 1021 D +m−2时饱和。XPS分析结果表明,氧化膜表面生成了FeOOD,但氧化膜中仍残留有纯Fe。这些事实表明氧化层的性质在氘捕获行为中起关键作用。
The ion fluence dependence of deuterium retention in SS-316 during oxidation at a temperature of 673K was studied to evaluate the dynamics of deuterium retention in the oxide layer of SS-316. The correlation between the chemical state of stainless steel and deuterium retention was evaluated using XPS and TDS. It was found that the major deuterium desorption temperatures were located at around 660K and 935K, which correspond to the desorption of deuterium trapped as hydroxide. The deuterium retention increased with increasing deuterium ion fluence, since the deuterium retention as hydroxide increased significantly. However, retention saturated at an ion fluence of ∼2.5×1021D+m−2. The XPS result showed that FeOOD was formed on the surface, although pure Fe also remained in the oxide layer. These facts indicate the nature of the oxide layer have a key role in deuterium trapping behavior.
