| 英文摘要 | Steel containers used for geological disposal of high-level radioactive waste will be gradually thinned or even perforated due to corrosion, which will lead to radiolysis of nuclides when they contact with infiltrated groundwater and produce H 2 O 2 . This work focused on investigating the influence of H 2 O 2 concentration (0%, 0.001%, 0.01%, 0.1% and 1% by volume) on the corrosion behavior of NiCu low alloy steel as the candidate material for containers was comparatively studied by combining corrosion weight loss test, corrosion product analysis, morphology characterization, thermodynamic analysis and electrochemical measurements. As [H 2 O 2 ] = 0.001%, H 2 O 2 inhibited the formation of gamma-FeOOH and enhanced the compactness of rust layer, which effectively blocked the migration of aggressive ions and slowed down the cathodic reduction reaction of rust, thus improving the corrosion resistance of NiCu steel. With the increase of [H 2 O 2 ] (0.01% -> 1%), the cathodic process of NiCu steel corrosion was promoted by the increase of dissolved oxygen involved in cathodic depolarization. Meanwhile, the relative content of Fe 3 O 4 in the rust increased, while Fe 6 (OH) 12 SO 4 and Fe 6 (OH) 12 CO 3 decreased obviously, which led to the loose and porous rust layer, thus accelerating the corrosion of NiCu steel. |
