Abstract

The effect of silicate less than several ppm in concentration on the rapid formation of a protective corrosion film on carbon steel in high-temperature water was investigated. Corrosion resistance decreased more slowly with time in the silicate solution than that in the distilled water at 90°C. Highly crystallized magnetite could readily be generated with 3.3 ppm silicic acid at 180°C. Since the morphology of the surface layer was significantly affected by the silicate concentration and temperature, optimum concentration of silicate at different temperatures could potentially mitigate the corrosion-related troubles in a nuclear power plant. The catalytic reaction among ferrous ion and silicates was explained by an olating reaction, where the hydroxyl ion plays an important role.
