摘　　要：采用自组装技术、交流阻抗法研究了对巯基苯硼酸对铝在3.5%NaCl溶液中的腐蚀行为.实验表明,随着对巯基苯硼酸浓度的变化和组装时间的不同缓蚀效率有所不同.当对巯基苯硼酸浓度为3.2×10-3mol/L,组装时间为12 h时腐蚀电流最小,缓蚀效率最高,达98%以上.The corrosion behavior of aluminum with 4-mercaptophenyl-boronic acid in a 3.5% NaCl solution was studied, using the self-assembly technology and EIS （electrochemical impedance spectroscopy）. The efficiency of corrosion inhibition was found to vary with the concentration of 4-mercaptophenyl-boronic acid and the assembly time. A 4-mercaptophenyl-boronic acid concentration of 3.2 × 10^-3 mol/L in combination with an assembly time of 12h was the optimum condition, under which the corrosion current was the smallest and efficiency was the highest （98%）.
