Resumen
A study on the use of Cynara scolymus (C. scolymus) as a green corrosion inhibitor for 1018 carbon steel in 0.5 M sulfuric acid has been carried out by using weight loss tests, potentiodynamic polarization curves and electrochemical impedance spectroscopy measurements. It was found that C. scolymus is a good corrosion inhibitor with its efficiency increasing with the inhibitor concentration but it decreases with an increase in the temperature.
