Liquid Sn corrosion behaviors to high-flux hydrogen plasmas irradiated Mo capillary-pore systems
This paper studied the effects of hydrogen plasma irradiation on the corrosion resistance of Mo capillary porous systems (CPSs) in high temperature liquid Sn. Initial Mo CPSs showed a significant morphology change and mass loss rate (1.107 × 10–3 mg/(mm2·h)) after corrosion in liquid Sn at 1,023 K f...

| description | This paper studied the effects of hydrogen plasma irradiation on the corrosion resistance of Mo capillary porous systems (CPSs) in high temperature liquid Sn. Initial Mo CPSs showed a significant morphology change and mass loss rate (1.107 × 10–3 mg/(mm2·h)) after corrosion in liquid Sn at 1,023 K for 100 h. A brief period of irradiation enhanced the corrosion resistance of Mo wires, resulting in a dramatic decrease to 1.23 × 10–4 mg/(mm2·h) in mass loss rate under the same corrosion conditions. To determine whether temperature was the main factor leading to above phenomenon, Mo CPSs were pre-annealed at the same temperature (843 K) as irradiation. The mass loss rate of annealed Mo CPSs (3.09 × 10–4 mg/(mm2·h)), which was lower than that of the initial sample, was still higher than that of the plasma-treated samples. Difference between plasma irradiation and heat treatment was the incident of various particles in hydrogen plasma. Therefore, the suppressed corrosion phenomenon caused by plasma could not only be attributed to the function of high temperature but its synergistic effect with hydrogen isotope retention. |
