| 摘 要： | 核桃（Juglans）叶提取物（JLE）可以作为“绿色”环保的植物缓蚀剂。本工作采用失重法和动电位极化曲线研究了JLE在1mol／LHCI溶液中对冷轧钢的缓蚀作用。结果表明，JLE对冷轧钢具有较好的缓蚀作用，且存钢表面的吸附符合校正的Langmuir吸附等温式，极化曲线表明，JLE为混合抑制型缓蚀剂。

| Abstract: | Juglans leaves extract(JLE) may be used as a good environmentally-friendly plant inhibitor.The inhibition effect of JLE on the corrosion of cold rolled steel(CRS) in 1.0 mol/L HCl was studied by weight loss and potentiodynamic polarization curve methods.The results show that JLE is a good inhibitor in hydrochloric acid for CRS,and the adsorption of the plant inhibitor on the CRS surface obeys the Langmuir adsorption isotherm equation.Polarization curves show that JLE is a mixed-type inhibitor. |
