| 摘 要： | 采用失重法和电化学方法研究了2种席夫碱类缓蚀剂N,N′-二水杨醛基-1，2-乙二亚胺（SB-Ⅰ）和水杨醛基吡啶-2-亚胺(SB-Ⅱ)在1 mol/L盐酸溶液中对A3碳钢的缓蚀性能。 失重实验表明，SB-Ⅰ和SB-Ⅱ在1 mol/L盐酸溶液中的浓度为20 mmol/L时，缓蚀效率分别达85%和92%。 经三电极体系极化曲线和交流阻抗谱测定实验表明，缓蚀性能是由于碳钢材料表面为缓蚀剂分子吸附所致，二者均属阴极型缓蚀剂。

| Abstract: | Inhibitory effects of two Schiff bases N,N′-bis(salicylidene)-1,2-ethylendiamine(SB-Ⅰ) and salcylidene-pyridine-2-yl-amine(SB-Ⅱ) on the corrosion of carbon steel in 1 mol/L HCl solution were studied via mass loss measurement method, polarization and electrochemical impedance spectroscopy. The results show that compounds SB-Ⅰ and SB-Ⅱ have fairly good inhibiting properties for carbon steel corrosion in hydrochloric acid with the best efficiencies of 85% and 92%, respectively, at 20 mmol/L additive concentration, and they belong to anodic inhibitors. |
