Effects of Different factors on Corrosion of Q235 Steel in H2S Solution

采用失重法和电化学方法研究了不同因素对Q235钢在H2S介质中腐蚀的影响,结果表明:H2S饱和的3%NaCl溶液中,Q235钢腐蚀速率随时间延长逐渐变小而后趋向平稳,随温度的升高出现先增大较快而后趋于平缓的变化规律;含3%NaCl的H2S溶液中,随着H2S浓度的增大,Q235钢的腐蚀速率出现先增大后减小的趋势。

Effects of different factors on corrosion of Q235 steel in H2S solution were studied by loss- weight test and electrochemical methods. The results showed that in H2S solution of 3%NaC1 the corrosion rate of Q235 steel decreased and became steady with time, of temperature, increased at first and decreased with increase of increased and became steady with increase H2S concentration.
