Abstract The efficiency of 1,3-bis-diethylamino-propan-2-ol (DEAP) as volatile corrosion inhibitor (VCI) for brass in simulated atmospheric water was studied by potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and gravimetric measurements. A significant decrease in the corrosion rate of brass was observed in the presence of DEAP. Polarization tests showed that the investigated compound was an anodic inhibitor, retarding the anodic dissolution of brass by blocking the active sites on the metal surface. The values of the charge transfer resistance, obtained from impedance plots of brass, increased with increasing inhibitor concentration and immersion time. The adsorption on the brass surface followed Langmuir adsorption isotherm model.

1,3-双-二乙氨基-丙-2-醇作为黄铜的挥发性缓蚀剂

摘要 通过动电位极化、电化学阻抗谱(EIS) 和重量测量研究了1,3-双-二乙氨基-丙-2-醇(DEAP) 作为黄铜挥发性腐蚀抑制剂(VCI) 在模拟大气水中的效率。在 DEAP 存在下观察到黄铜的腐蚀速率显着降低。极化测试表明，所研究的化合物是一种阳极抑制剂，通过阻断金属表面的活性位点来延缓黄铜的阳极溶解。从黄铜阻抗图中获得的电荷转移电阻值随着抑制剂浓度和浸渍时间的增加而增加。黄铜表面的吸附遵循朗缪尔吸附等温线模型。
