Use of Rosa canina fruit extract as a green corrosion inhibitor for mild steel in 1 M HCl solution: A complementary experimental, molecular dynamics and quantum mechanics investigation

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