英文摘要：

The effect of alloying elements and microstructure on CO2 corrosion of steels was reviewed. The review discussed the relations of morphology, structure and protection property of CO2 corrosion scale to composition and microstructure of steel. The present electrochemistry investigation status of CO2 corrosion was also analyzed. Then the difficulty and key directions for further investigations were pointed out.
