摘要
Abstract
The corrosion behavior of Q345R steel at different temperatures,CO2 and H2S partial pressure ratios was simulated by hightempera-ture and highpressure reactor and electrochemical workstation.The results show that the average corrosion rate increases as the temperature in-creases.At the temperature of 20℃ and 50℃,both CO2 and H2S have greater solubility,and the solution has a lower pH value,therefore,with the increase of CO2/H2S concentration,the uniform corrosion rate of Q345R steel increases significantly.The results of microscopic morphology and XRD analysis showed that H2S corrosion was dominant.关键词
