摘要

研究了在含300 ppm SO2杂质和不含300 ppm SO2的水饱和超临界CO2 （SC CO2）和CO2饱和水相环境中3Cr2Al钢腐蚀产物膜的形成机理。在水饱和的SC CO2相中，SO2通过增加H2O在体系中的溶解度和引起液膜酸化来加速腐蚀。在co2饱和的水相中，发现SO2不会引起侵略性腐蚀，而是通过形成致密的硫（so0）保护膜来显著抑制腐蚀进程。提出了SO2与Cr/Al合金元素协同作用的机理来解释其缓蚀作用。

Effects of SO2 impurity on corrosion behaviors of novel 3Cr2Al alloy steel in supercritical CO2 brine environment

The formation mechanisms of corrosion product films on 3Cr2Al steel in water-saturated supercritical CO₂ (SC CO₂) and CO₂-saturated aqueous-phase environments with and without 300 ppm SO₂ impurities were investigated. In the water-saturated SC CO₂ phase, SO₂ accelerates corrosion by increasing the solubility of H₂O in the system and causing the acidification of the liquid film. In the CO₂-saturated aqueous phase, it was found that SO₂ did not cause aggressive corrosion but rather significantly inhibited corrosion progress by forming a dense sulfur (S⁰) protective film. A mechanism based on the synergistic interaction of SO₂ and the Cr/Al alloying elements was proposed to explain the inhibition of the corrosion.
