摘要
在模拟海水环境中研究了低碳钢和两种含有 Cu-Sb 和 Cu 的新型低合金耐腐蚀钢的耐腐蚀性。通过电化学试验和加速腐蚀试验分析了 Cu 和 Sb 对耐腐蚀性的影响。结果表明，Cu 和 Sb 可通过提高腐蚀电位和增加极化电阻来降低腐蚀电流密度。Sb 能促进形成具有较强缓蚀性能的含 Cu 化合物，并能增强钢的整体耐腐蚀性。此外，Sb 还能促进 Fe2+ 离子转化为耐腐蚀化合物 α-FeOOH，从而进一步提高钢的耐腐蚀性。
Research on the Chloride Ion Corrosion Resistance of Cu-Sb-Added Low-Carbon Steel
The corrosion resistance of low-carbon steel and two new low-alloy, corrosion-resistant steels containing Cu-Sb and Cu was studied in a simulated seawater environment. The effects of Cu and Sb on corrosion resistance were analyzed by an electrochemical test and accelerated corrosion test. The results show that Cu and Sb reduce the corrosion current density by increasing the corrosion potential and increasing the polarization resistance. Sb can promote the formation of Cu-containing compounds with a strong corrosion inhibition performance, and it can enhance the overall corrosion resistance of steel. In addition, Sb can also promote the conversion of Fe2+ ions into a corrosion-resistant compound, α-FeOOH, and it also further improves the corrosion resistance of steel.
