Influence of Deteriorated Bentonite Sediments on the Corrosion Behavior of NiCu Low Alloy Steel

The corrosion evolution of steel disposal container largely depends on the surrounding bentonite environment in long-term geological high-level radioactive wastes. This study focused influence deteriorated sediments behavior NiCu low alloy top supernatant and bottom slurry formed by Gaomiaozi 0.05 M NaHCO3 + 0.1 NaCl Na2SO4 solution. In supernatant, cathodic process was transformed from reduction oxygen to ferric products with time as same that blank While slurry, always maintained hydrogen reaction due coverage more sediments. Meanwhile, rate obviously decreased. addition, localized tendency could also be reduced large amount
