| 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API P105钢的电化学腐蚀行为的影响.结果表明,随着NaCl含量的增大,P105钢的腐蚀电位正移,抑制了腐蚀过程的阴阳极反应,降低了P105钢的腐蚀速率.分析表明,Cl在API P105钢表面的吸附为Temkin等温吸附.

| Abstract: | The effect of NaCJ on the corrosion behavior of API P105 steel in the C02-saturated solution was studied by electrochemical impedance spectrum(EIS) and polarization measurement. The results showed the increase of NaCl concentration decreased the the corrosion rate of the steel, which could be attribulted the decrease of hydroxide ion concentration and the dissolution of C02, and the adsorption of Cl- obeyed the Tem- kin isotherm. |
