摘要
主要介绍了超临界二氧化碳环境下耐热材料的抗腐蚀性能,重点阐述了超临界二氧化碳温度、压力、杂质气体H2O和含硫气体对耐热材料腐蚀行为及抗腐蚀性能的影响规律;同时论述了超临界二氧化碳关键高温部件材料选型及其腐蚀机理研究。最后介绍了耐热材料在超临界二氧化碳中的腐蚀机理及未来的研究方向。
This paper introduced the corrosion resistance of heat-resisting materials in supercritical carbon oxide. The effects of temperature, pressure, foreign gas H2 O and sulfurous gas on the corrosion behavior and corrosion resistance were focused. Moreover, materials selection and corrosion mechanism in supercritical carbon dioxide system were discussed. Lastly, the corrosion mechanism and research direction of materials in supercritical carbon dioxide were introduced.
