高温超临界CO2腐蚀的研究现状与进展
Current States and Research Progress of High Temperature Supercritical CO2 Corrosion
摘要
Abstract
As the energy transfer medium in Brayton cycle,Supercritical CO2 enjoys the merits of high efficiency and high stability.However,the coupled oxidation and carburization induced by high-temperature supercritical CO2 cause great threat to the safe operation of the system.Identifying the corrosion features and affecting factors,and selecting suitable construction materials in supercritical CO2 environment play an important role in stable operation of Brayton system.Therefore,this article analyzes the corrosion feature of Supercritical CO2 as coupled oxidation and carburization,elucidates the corrosion effects of different environmental factors(temperature,pressure and environment chemistry),summarizes the corrosion performance and degradation rate of commonly used Fe-based alloys(ferritic steels,martensitic steels,austenitic steels),Ni-based alloys and other alloys,and introduces the related corrosion protection methods.The related research aims to provide theoretical foundation and technical guidance for the corrosion protection for the high-temperature supercritical CO2 system.关键词
