Özet

In this study, the inhibitory effect of 1H-benzimidazole, 2-methyl-1H-benzimidazole and 5-nitrobenz imidazole on zinc have been investigated. Method: For this purpose, we used current-potential and Electrochemical Impedance Spectroscopy (EIS) methods in 0.5M NaCl solution at 25°C. Zinc polished with sand paper, etched 20 minute in 0.15 M HCl solution, cleaned with distilled water immersed for pre-treatment with sodium hydrogen phosphate (Na2HPO4.12H2O, pH 5.7) and sodium silicate (Na2SiO2) solution. Findings: Pre-treated coatings on the zinc increased inhibition effects of BIM derivatives. Inhibition efficiency was approximately 98%, for 1H-benzimidazole and 5-nitrobenzimidazole.
