The supercritical carbon dioxide (S-CO2) cycle power generation technology has become an epoch-making and revolutionary frontier technology in the field of thermal power generation because of its own technical advantages. Due to the very harsh working environment, S-CO2 is easy to cause corrosion problems of equipment materials. In order to ensure the safe and effective operation of S-CO2 system, the range of working medium parameters and candidate materials of the system’s key equipment are introduced. The current research status of corrosion behavior of metal materials in S-CO2 environment are then reviewed. The corrosion mechanism in S-CO2 carbon environment is elaborated in detail. The influences of temperature, pressure, impurities, flow rate and material composition on S-CO2 corrosion process are summarized. Meanwhile, the research progress of S-CO2 corrosion prevention and control technology is introduced. Finally, the shortcomings of existing research and the main direction of future research wereare summarized, so as to provide scientific basis for the safe operation of S-CO2 recycling system in China.
