摘要

通过实验、热力学和分子动力学研究了在 650 ℃ 的过温条件下，P92 钢在二氧化碳中形成氧化鳞片剥离的机理。在 P92 钢上形成了内层为 FeCr2O4 鳞片、外层为 Fe3O4 鳞片的双相氧化物鳞片，其中在 Fe3O4 氧化物中观察到蜂窝状孔隙。P92 钢上的蜂窝状孔隙大小和 CO 气体生成率在 80 分钟后达到最大值。根据蜂窝孔中碳的沉积情况，Fe3O4 氧化物鳞片的剥离分为两个阶段。

Understanding the Corrosion Behavior of P92 Steel in CO2 Using In-Situ Monitoring Technology II: Mechanism of Oxide Scale Peeling

The mechanism of oxide scale exfoliation from P92 steel during formation in CO₂ under over-temperature conditions at 650 ℃ was studied by the experiments, thermodynamics, and molecular dynamics. A duplex oxide scale with an inner FeCr₂O₄ scale and an outer Fe₃O₄ scale was formed on P92 steel, in which honeycomb pores were observed in Fe₃O₄ oxides. The honeycomb pore size and CO gas generation rate on P92 steel showed maximum values after 80 min. The exfoliation of Fe₃O₄ oxide scale was divided into two stages based on the deposition of carbon in the honeycomb pores.

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.
