摘要

利用原位监测技术研究了 P92 钢在高温 CO2 中的腐蚀过程中的碳迁移和地下转化。在监测反应过程中，使用中间 CO 来区分氧化反应和碳化反应。P92 钢在 550 °C 和 600 °C 下的 CO 生成率分别在 80 分钟和 100 分钟后达到最高值。观察发现，Fe3O4 氧化物鳞片上的蜂窝状孔隙是 CO2 和 CO 气体扩散和碳沉积的主要通道。沉积的碳以离子状态逐渐扩散到基体中，并转化为碳化物。

Understanding the Corrosion Behavior of P92 Steel in CO2 Using In Situ Monitoring Technology I: Mechanism of Carbon Migration and Transformation

Carbon migration and subsurface transformation, among the corrosion processes of P92 steel in high-temperature CO₂ were investigated using in situ monitoring technology. During monitoring reaction intermediate CO was used to distinguish between the oxidation and carbonization reactions. The CO generation rate on P92 steel at 550 °C and 600 °C reached the highest value after 80 min and 100 min, respectively. Honeycomb pores in Fe₃O₄ oxide scale were observed as the main channels for CO₂ and CO gas diffusion and carbon deposition. The deposited carbon gradually diffused into the matrix in an ionic state and transformed into carbides.

期刊介绍： Oxidation of Metals is the premier source for the rapid dissemination of current research on all aspects of the science of gas-solid reactions at temperatures greater than about 400˚C, with primary focus on the high-temperature corrosion of bulk and coated systems. This authoritative bi-monthly publishes original scientific papers on kinetics, mechanisms, studies of scales from structural and morphological viewpoints, transport properties in scales, phase-boundary reactions, and much more. Articles may discuss both theoretical and experimental work related to gas-solid reactions at the surface or near-surface of a material exposed to elevated temperatures, including reactions with oxygen, nitrogen, sulfur, carbon and halogens. In addition, Oxidation of Metals publishes the results of frontier research concerned with deposit-induced attack. Review papers and short technical notes are encouraged.
