Hydrogen isotope retention of reduced activation ferritic steel with surface damage

研究了预致表面损伤对还原活化铁素体钢氢同位素解吸/保留性能的影响。将还原活化的铁素体钢F82H辐照到氦离子或氢离子/等离子体中。然后，研究了诱导表面损伤与氢同位素保留/解吸性能的关系。表面损伤层的引入和（或）等离子体/离子辐照改变杂质分布等表面改性对铁素体钢氢同位素保留/解吸性能有显著影响。

The effects of surface damage induced in advance on hydrogen isotope desorption/retention properties of reduced activation ferritic steel were investigated. The reduced activation ferritic steel, F82H, was irradiated to helium or hydrogen ions/plasma. Then, the relation of the induced surface damage with properties of the hydrogen isotope retention/desorption was examined.The introduction of surface damage layer and/or surface modification such as change in impurity distribution by plasma/ion irradiation significantly affected the properties of hydrogen isotope retention/desorption of the ferritic steel.
