摘要

The integral effects of Ca and Sb on the corrosion properties of E690 steel were studied in a simulated tropical marine environment through immersion and dry/wet cyclic tests, focusing on localized and long-term corrosion properties. Results showed that Ca improved the corrosion resistance of steel by modifying the MnS inclusion into MnS-CaAl₂O₄ inclusion, and Sb enhanced the consumption of H⁺ to decrease the electrochemical activity on steel surface. The protectiveness of the rust layer was increased by the enrichment of Ca and Sb, and the alkalization caused by Sb promoted appositional enrichment of Sb and Ca in the rust layer.
