AbstractThe corrosion behaviors of low carbon steel, a kind of materials used in making metal container sealing high-level radioactive waste, in three deaerated bicarbonate solutions simulated the ground water, 0.1 mol/L NaHCO3 solution, 0.1 mol/L NaHCO3+0.1 rnol/L Na2SO4 solution and 0.1 mol/L NaHCO3+0.1 mol/L NaCl solution, were examined. The results in potential evolution revealed that the low carbon steel moved up to the passive state in 0.1 mol/L NaHCO3 solution while moved up to the re-active state in the other solutions. SEM observations showed that the low carbon steel was not corroded in 0.1 mol/L NaHCO3 solution, while homogeneous corrosion occurred in 0.1 mol/L NaHCO3+0.1 mol/L Na2SO4 solution and local corrosion in the third solution. XRD analyses illustrated that the corrosion products are composed of Fe3O4 and alpha-FeOOH.
