Abstract
The inhibitory performance of quince extract (QE) on the corrosion and electrochemical properties of low-carbon steel in 1 molar hydrochloric acid was studied by electrochemical methods and weight loss measurement. The chemical compounds contained in quince that offer substantial corrosion inhibition impacts (e.g., amino acids and flavonoids) were examined by Fourier-transform infrared spectroscopy and ultraviolet. Polarization tests and electrochemical impedance spectroscopy results showed that increasing the concentration of the extract in the range of 200–1200 ppm increased its inhibition efficiency. The highest inhibition efficiency of the extract based on polarization and EIS results was respectively 95% and 93.0%, both observed at a concentration of 1200 ppm. Based on the results, quince extract was considered as a mixed-type corrosion inhibitor. Scanning electron microscopy and atomic force microscopy of the surface of steel specimens immersed in 1 M HCl without and with 200–1200 ppm of the inhibitor showed the effectiveness of quince extract in preventing corrosion.
