The inhibition efficiency (IE) of Eucalyptus Camaldulensis Extract (ECE) in controlling corrosion of carbon steel in well water in the presence and absence of Zn2+ has been evaluated by weight loss method. The formulation consisting of 8 mL of Eucalyptus Camaldulensis Extract (ECE) and 5 ppm Zn2+ offers 98 % inhibition efficiency to carbon steel immersed in well water. Potentiodynamic polarization study reveals that this system formulation acts as mixed type inhibitor. AC impedance confirms that compact protective film is formed on the metal surface. The surface morphology of inhibited and uninhibited carbon steel is also analyzed by Scanning Electron Microscopy (SEM). Keywords: Corrosion inhibition, Carbon steel, Eucalyptus Camaldulensis Extract.
