Abstract

A Type 430 stainless steel was exposed to Ar-20 %CO₂ without and with water vapour at 800 °C up to 96 h. Increasing water vapour content from 5 % to 40 % helped reduce mass gain, enhance volatilisation, and improve scale adhesion with fewer pores at scale/steel interface. Mechanisms for Cr and Mn volatilisations including the direct reactions between Cr-containing oxide and CO₂ were suggested with the aid of the XPS results. Mathematical relations that express the role of water vapour on concentrations of defects responsible for scale growth were proposed to help explain the reduced oxidation rate.

二氧化碳和水蒸气对430型不锈钢作为生物气体燃料中温sofc互连的高温腐蚀的作用

430型不锈钢暴露于Ar-20 %CO2中，在800°C下，不含水蒸气，最长可达96 小时。将水蒸气含量从5 %增加到40 %有助于减少质量增加，增强挥发性，改善水垢与钢界面的粘附性，减少水垢与钢界面的孔隙。结合XPS结果，提出了Cr和Mn挥发的机理，包括含Cr氧化物与CO2的直接反应。提出了表达水蒸气对导致水垢生长的缺陷浓度的作用的数学关系，以帮助解释氧化率的降低。
