| 英文摘要 | Domestic and foreign researches on the corrosion behavior of low carbon steel canister in high level nuclear waste geological repositories focus on the initial aerobic stage and the later anaerobic stage, while few researches have been reported on the corrosion behavior during the disposal transition period. The long term electrochemical corrosion behavior of X65 low carbon steel in 80 degrees C Gaomiaozi bentonite saturated with anaerobic Beishan groundwater has been studied by electrochemical measurement system in anaerobic glovebox constructed independently. The results indicated that the open circuit potential of X65 low carbon steel decreased gradually during 150 d, while the electrochemical impedance of the corrosion film increased with immersion time. Pitting corrosion occurred at the beginning of immersion tests, and finally transformed into general corrosion. Morphologies, compositions, and phases of the corrosion film formed on the carbon steel surface were examined by SEM, EDS and mu-XRD. The results showed that the corrosion film was mainly composed of blocks, slices, rods and swellings. The elemental distribution in the corrosion film was uniform, and the phases were composed of magnetite and hematite. The average corrosion rates were detected by weight loss measurement, which decreased from 195.88 mu m/a to 20.58 mu m/a. The corrosion rates (V) followed a power function pattern V=8.34t(-0.88), indicating that the film growth process was controlled by oxygen diffusion. |
