摘要

采用材料失重、动电位极化和电化学交流阻抗技术,分别测试了温度为30 ℃,浓度为1.0 mol·L-1盐酸溶液中不添加和添加银纳米颗粒时铝的腐蚀速率. 结果表明,当银纳米颗粒的浓度为0.014 g·L-1时,其防护效率达96.4%. 随着银纳米颗粒的浓度增大,铝/溶液界面的双电层电容值减小,说明铝的表面发生了银纳米颗粒的吸附. 朗缪尔吸附等温方程和动力学-热力学模型均可以较好地拟合所得到的实验数据. 为了确认铝金属表面与银纳米颗粒的相互作用类型,得到了铝的零电荷电位值. 研究发现,通过扫描电子显微镜和能量散射X-射线能谱分析,并结合电化学实验后铝电极表面的外观观察,可以很好地解释材料失重和电化学测试得到的数据.

Abstract

The mass loss, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) techniques were used for the determinations of the corrosion rates for aluminium in 1.0 mol·L-1 hydrochloric acid (HCl) solutions both in the absence and presence of silver nanoparticles (SNPs) at 30 ℃. The protection efficiency was evaluated to be 96.4% for 0.014 g·L-1 of the SNPs. It has been found that the capacity of the electrical double layer at the aluminium/solution interface was decreased with increasing the concentration of the SNPs, indicating that the SNPs were adsorbed at the aluminium surface. The Langmuir adsorption isotherm and the kinetic-thermodynamic model were fitted to the experimental data. The potential of zero charge (PZC) for aluminium was determined in order to clarify the type of interaction between the metal surface and the SNPs. The experimental data obtained by scanning electron microscopy (SEM) and energy-dispersive X-ray (EDX) spectroscopy, together with the visual inspections at the surfaces of the aluminium electrodes after the electrochemical tests, all gave very good support to those obtained by the mass loss and electrochemical measurements.
