Corrosion inhibition effect of <i>Cycas revoluta</i> leaves extract on corrosion of soft?cast steel in hydrochloric acid medium

The inhibition action of environmentally sustainable inhibitor Cycas revoluta leaves extract (CRLE) for corrosion protection soft-cast steel in a solution HCl was assessed with electrochemical and chemical methods. eco-friendly forms thin coating on slows the acid media. percent performance, current density, potential, both anodic cathodic slopes Tafel were calculated. results research are beneficial correlation each other. inhibitor's inhibitory ability well illustrated by CRLE adsorption followed Langmuir isotherm. investigations reveal that is mixed form inhibitor. Studies performed varying amounts temperatures. Thermodynamic parameters calculated, it shows effect spontaneous exothermic. interaction plant characterized SEM, FTIR, contact angle measurements, AFM techniques.
