摘要:
针对石油加工过程中的NH4Cl腐蚀，采用三电极体系，通过电化学检测分析了NH4Cl浓度对纯镍腐蚀行为的影响。通过电化学阻抗谱(EIS)、动电位扫描曲线、EDS和SEM等检测方法，研究了纯镍在NH4Cl溶液中的腐蚀行为。结果表明：随NH4Cl浓度增加，纯镍的开路电位负向移动，EIS对应的Nyquist曲线图的圆弧半径降低，低频区由Warburg阻抗转变为电感；Cl?浓度增加使钝化区范围变窄，降低了维钝电压，升高了维钝电流密度，纯镍表面腐蚀坑尺寸变大。因此，随着NH4Cl浓度增加，纯镍的腐蚀过程发生变化且耐蚀性显著降低，金属镍更适宜服役于较低NH4Cl浓度的工况中。
Abstract:
To address the NH4Cl corrosion in the petroleum processing, a three-electrode system was adopted and the effect of NH4Cl concentration on the corrosion behavior of pure nickel was analyzed through electrochemical detection. The corrosion behavior of pure nickel in NH4Cl solution was investigated by electrochemical impedance spectroscopy (EIS), potentiodynamic scanning curves, SEM and EDS. The results show that with the increasing in NH 4Cl concentration, a negative shift is observed in open circuit potential of pure nickel, accompanied by EIS by a decrease in the arc radius of the corresponding Nyquist curve and a change in the low-frequency region from Warburg impedance to inductance. The increasing in Cl ? concentration results in a narrowing of the passivation region, a decrease in the passivation voltage, and an increase in the passivation current density. The size of corrosion pits on the surface of pure nickel becomes larger. With increasing of NH 4Cl concentration, the corrosion process of pure nickel is changed, and the corrosion resistance is significantly decreased. Therefore, metallic nickel is considered more suitable for service in the working conditions with lower NH4Cl concentrations
