Hydrogen charging process instrument

Successful results of hydrogen charging were obtained for ODS-EUROFER steel, which is one of the most promising structural materials for fusion reactors and Gen-IV nuclear reactors. The suitable parameters of hydrogen charging were found experimentally. The plasma exposure time for homogenization of hydrogen concentration in the certain shape of the specimen of the ODS-EUROFER steel was determined to be more than 30 min. Comparative study of the surface morphology of the specimens before and after hydrogen plasma charging was performed by means of scanning electron microscopy (SEM).
