Abstract
The inhibiting action of Ficus carica and Olive extracts on the corrosion process of zinc in 2.0 M HCl solution has been investigated by weight loss, open –circuit potential and potentiodynamic polarization measurements. The results revealed that, the highest efficiency (IE%) was observed at 20.0 g/l of inhibitor. Langmuir isotherm was investigated to clarify the nature of adsorption. The values of are low revealed to a physical adsorption of the extracts on the zinc surface. The effect of temperature range (25-55ºC) supporting the proposed physical adsorption. Electrochemical behaviour indicated that the extract act as anodic- type inhibitors.
