Abstract Rosa canina fruit extract was utilized for mild steel corrosion inhibition in 1 M HCl solution. The inhibition efficiency of inhibitor was studied by electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization test. Results revealed that R. canina fruit extract acted as a mixed type inhibitor and remarkably reduced the corrosion current density of mild steel from 110 μA/cm2 (0 ppm) to 44 μA/cm2 (800 ppm). The maximum corrosion inhibition efficiency (about 86%) was obtained using 800 ppm inhibitor. The inhibitor adsorption on the mild steel surface significantly increased the water contact angle (about 50%).

使用犬蔷薇果实提取物作为 1 M HCl 溶液中低碳钢的绿色缓蚀剂：补充实验、分子动力学和量子力学研究

摘要 犬蔷薇果实提取物用于在 1 M HCl 溶液中抑制低碳钢腐蚀。通过电化学阻抗谱(EIS)和动电位极化试验研究了缓蚀剂的缓蚀效率。结果表明，R. canina 果实提取物作为一种混合型抑制剂，将低碳钢的腐蚀电流密度从 110 μA/cm2 (0 ppm) 显着降低至 44 μA/cm2 (800 ppm)。使用 800 ppm 抑制剂获得最大腐蚀抑制效率（约 86%）。缓蚀剂在低碳钢表面的吸附显着增加了水接触角（约 50%）。
