Rosa canina fruit extract was utilized for mild steel corrosion inhibition in 1 M HCI 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 mu A/cm(2) (0 ppm) to 44 mu A/cm(2) (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%). (C) 2018 The Korean Society of Industrial and Engineering Chemistry.
