Abstract
Inhibition efficiencies of Ocimum basilicum and Cucurbita pepo extracts on low carbon steel corrosion in industrial water have been investigated using mass loss, potentiodynamic polarization, impedance spectroscopy and SEM. It was found that the plant extracts chosen revealed good performance as green inhibitors for low carbon steel in industrial water, and their inhibitive performance improved with increasing concentration up to critical values of 2.96 and 5.25 g L-1 for Cucurbita and Ocimum, respectively. Thermodynamic parameters were evaluated and discussed. SEM was carried out to characterize the film formed on the metal surface
