| Abstract: | The corrosion environment of cargo oil tank (COT) was simulated according to performance standard for corrosion resistant steel of IMO in this paper, to study the corrosion behavior of two different ship hull steel on the upper deck of COT. The results showed general corrosion in wet-dry environments contained H2S, the corrosion rate of conventional E36 steel reached 0??4mm/a. The addition of Cu and Ni improved the formation of the stable phase ??-FeOOH, which decreased the defect in the rust and made the rust more compact. Inclusions such as CaO and CaS formed in the Ca treated ship steel, which dissolved under the corrosion media and alkaline product generated, the alkaline product increased the pH value of the liquid film on the surface of steel and slowed down the corrosion rate of steel. |
