| 摘 要： | 利用动电位极化和电化学阻抗技术研究了温度对N80钢在CO2饱和的NaCl溶液中腐蚀过程的影响。结果表明，温度的升高促进了腐蚀反应的阳极过程和阴极过程，使得N80钢腐蚀速率增大，而且温度对阴极过程的促进作用大于阳极过程，导致了Ecorr的正向移动。温度的升高并没有改变腐蚀机理；在温度较低的环境中，电化学阻抗谱呈现3个时间...

| Abstract: | The effect of temperature on corrosion behavior of N80 steel in CO_2 saturated NaCl solution was investigated by dynamic polarization and electrochemical impedance spectroscopy(EIS).The results show that the EIS has three time constants for the capacitance at high frequency,the inductance at middle and low frequency and the capacitance at low frequency.The capacitance at high frequency is related to the capacitance of the double layer and transfer resistance,the inductance is attributed to the coverage of t... |
