Abstract :

In this study the electrochemical behavior of the imidazole as a self -assembled inhibitor on hybrid coating prepared by sol - gel with immersion method on carbon steel deposition was studied. It was observed that corrosion resistance of coating based on hybrid 3-methacryloxy propyltrimethoxysilane significantly increased in the presence of imidazole inhibitor. In order to prepare hybrid coatings 3-methacryloxy propyltrimethoxysilane specified ratios were combined with ethanol and distilled water. Mild carbon steel before applying the hybrid coating was immersed in different concentrations solutions of 0.001, 0.01 and 0.1 M of imidazole inhibitor. Self-assembled film of imidazole was formed on the surface of the substrate. The morphology of the coating was studied by scanning electron microscopy. The impact of the self-assembled film of inhibitor was examined on anti-corrosion properties of coating for different concentration of inhibitor in hydrochloric acid as well as corrosive environment. Potentiodynamic polarization test and SEM technique characterization were compared by original carbon steel samples. It Was determined that adding the corrosion inhibitor to protect system of the carbon steel, the inhibition efficiency improved corrosion resistance up to 97%  in 0.5 M of hydrochloric acid.
