Abstract::The plant extracts are eco-friendly, acting as a corrosion inhibitor for mild steel (MS) in 1N HCl acidic medium. In this study, Mallotusphilippensis leaves (MPL) extract was used which acted as corrosion inhibitorfor MS. The inhibition efficiency was tested for MPL corrosion inhibitor by weight loss method, various immersion time and varying the temperature (313 K to 353 K) at different concentration. The FTIR results showedvarious functional group are being adsorbed on the metal surface. The surface analysis was carried out by using EDXand SEM techniques. The electrochemical techniques were conducted byPotentiodynamic polarization method and Electrochemical impedance spectroscopy at room temperature.
