Synergistic effect of aluminum lactate and sodium molybdate on freshwater corrosion of carbon steel under irradiation

Otani, Kyohei ; Kato, Chiaki ; Igarashi, Takahiro

A novel corrosion inhibitor of carbon steel in fresh water using Al lactate was proposed and its corrosion-inhibition mechanism was investigated. 0.75 mM Al lactate and 0.25 mM sodium molybdate were the most inhibitive to the corrosion of carbon steel in 3 mM NaCl. Al $^{3+}$ and MoO $_{4}$ $^{2-}$ in solution formed the metal cation layer on carbon steel with few defects, and the layer did not contain Fe. The metal cation layer on carbon steel inhibited both the cathodic oxygen reduction reaction and anodic iron dissolving reaction and thus enhances the corrosion protection of carbon steel in fresh water.
