Abstract:
The purpose of this study was to evaluate the effectiveness
of organic inhibitor to slow down or inhibit the mild steel
corrosion caused by red sea environment.
2-aminobenzimidazole (2-ABA) was used as inhibitor,
corrosion was evaluated through weight loss determination and
electrochemical techniques. The results obtained revealed that
2-ABA is a mixed inhibitor. The extent of inhibition reached
97.53% at the highest concentration of the inhibitor.
Morphological analysis of mild steel specimens using
scanning electron microscopy (SEM) and Energy Dispersive x-
ray spectroscopy (EDAX) provide supportive evidence for the
formation of film that retards corrosion process.
Further evidence was derived from IR spectra which
showed shift or disappearance of peaks indicating the binding
between inhibitor and mild steel surface.
