Abstract

Generating robust FeCO₃ films on steel is crucial to prevent CO₂ corrosion. Here, FeCO₃ film was proved to be vulnerable to temperature drops and preferentially destabilized from grain gaps and crystal defects, or due to a local variation of solution chemistry. By properly tailoring the solution volume and extending the exposed time, a densified and uniform FeCO₃ film could be generated, performing satisfied durability against corrosion at lower temperatures. We identified a Warburg impedance fitted from in-situ EIS higher than a critical value sustaining the long-term stability of FeCO₃ films, which can guide the corrosion management in CO₂ transportation.

老化FeCO3薄膜在含约束自由水的致密相CO2环境中减轻温度下降对钢的腐蚀

在钢上生成坚固的FeCO3薄膜对于防止二氧化碳腐蚀至关重要。在这里，FeCO3薄膜被证明容易受到温度下降的影响，并且由于晶粒间隙和晶体缺陷或由于溶液化学的局部变化而优先失稳。通过适当调整溶液体积和延长暴露时间，可以生成致密均匀的FeCO3膜，在较低温度下具有良好的耐腐蚀性能。我们发现原位EIS拟合的Warburg阻抗高于维持FeCO3膜长期稳定性的临界值，这可以指导CO2运输中的腐蚀管理。
