| 摘 要： | 用电化学阻抗谱(EIS)和极化测量，研究了在含CO2的溶液中NaCl含量对N80钢的电化学腐蚀行为的影响．结果表明，随着NaCI含量的增大，N80钢的腐蚀电位正移，抑制了腐蚀过程的阴阳极反应，降低了N80钢的腐蚀速率．分析表明,Cl-在N80钢表面的吸附为Temkin等温吸附．

| Abstract: | The effect of NaCl on the corrosion behavior of N80 steel in the CO_2-saturated solution was studied by electrochemical impedance spectrum(EIS) and polarization measurement. The results shows that the increase of NaCl concentration decreases the corrosion rate of the steel, which could be attributed to the decrease of hydroxide ion concentration and the dissolution of CO_2, and the adsorption of Cl~- on the surface of N80 steel is described by the Temkin isotherm. |
