Inhibitation of zinc corrosion in the red sea water

Abstract EN

Zinc corrosion in the Red sea water without and with three corrosion inhibitors viz Mercaptotraizole (MTRA), Benzotraizole (BTRA) and Bezimidazole (BZL) was investigated using different techniques i.e.

weight loss, linear* and logarithmic polarization beside the electrochemical impedance spectroscopy (EIS).

The inhibition efficiency calculated was found to be in the order : BZL > BTRA > MTRA, The scanning electron microscope (SEM) images supported the formation of a protective film on the metal surface thus retarding its corrosion.
