Eucalyptus Extract as Eco-Friendly Inhibitor for the Corrosion of Steel

The objective of this study was to evaluate the potential of Eucalyptus plant extract as a green inhibitor for carbon steel in 1M HCl acid medium. The leaves of the Eucalyptus plant were extracted and tested for their inhibitory effect on carbon steel using the mass loss method. The results showed that the maximum inhibitory efficiency of 92.79% was achieved with a concentration of 4.28 g/L of the Eucalyptus extract at room temperature. DRX characterization was conducted on steel electrodes before and after 24 hours of immersion in 1M HCl solution, both in the absence and presence of the Eucalyptus extract. This analysis aimed to examine any structural changes in the steel electrodes caused by corrosion and the presence of the green inhibitor.
