摘要
采用交流阻抗技术研究了净化水中氟离子对Q235的腐蚀过程,并根据电化学阻抗谱理论推导了氟离子对Q235的腐蚀机理。结果表明,Q235的腐蚀过程包括两个电极反应过程,其中铁配体的失电子过程为整个反应的速度控制步骤。
The corrosion process of Q235 steel induced by fluorine ions in the purified water has been investigated with the AC Impedance technique,and the corrosion mechanism induced by fluorine ions was deduced by the electrochemical impedance spectroscopy theory.The result showed that the corrosion process of Q235 steel includes two electrode reaction processes,wherein the electron-missing process of Q235 steel is the speed control procedure of the whole reaction.
