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。
J uglans 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 HCI was studied by weight loss and potentiodynarnic 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.
