    CORROSION INHIBITION OF AISI 1007 STEEL IN HYDROCHLORIC ACID USING CUCUMIS SATIVUS (CUCUMBER) EXTRACTS AS GREEN INHIBITOR

    The inhibiting effect of cucumber peel and seed extracts on corrosion of AISI 1007 steel in 2M solution of Hydrogen Chloride (HCl) at ambient temperature was studied using gravimetric and electrochemical measurements (TAFEL polarization). It was observed that corrosion rates reduced with increase in the extracts’ concentration, and inhibition efficiency (IE%) increased with the concentration. The study revealed that the cucumber extracts possessed good inhibiting efficiency. Though, the cucumber peel extract’s efficiency was greater than that of the seed (oil) extract during gravimetric measurement. The highest inhibition efficiency (IE) of 86.63% was achieved using the cucumber peel extract as inhibitor with 1.0 g/l concentration, while cucumber seed (oil) extract recorded 39.23%. The electrochemical measurements (TAFEL polarization) results revealed that the corrosion current density decreased with the increased in the concentration of the cucumber peel extract. The decreased in corrosion was due to increased blocking of the metal surface by adsorption of the leaf extract. Therefore, the extracts could be used as a green inhibitor to the corrosion of AISI 1007 steel in the hydrochloric acid medium as a replacement for toxic inhibitors.
