Corrosion Inhibition Study of Mild Steel in an Aqueous Hydrochloric Acid Solution Using Brilliant Cresyl Blue - a Combined Experimental and Monte Carlo Study. Port. Electrochim. Acta [online]. 2021, vol.39, n.6, pp.393-401.  Epub 31-Dic-2021. ISSN 0872-1904.  https://doi.org/10.4152/pea.2021390601.

Mild steel corrosion behaviour in a 0.5 M hydrochloric acid aqueous medium has been studied using potentiodynamic polarization measurements and Monte Carlo calculations, in the presence and absence of (7-Amino-8-methylphenoxazin-3-ylidene)-diethylazanium dichlorozinc dichloride [known as Brilliant Cresyl Blue (BCB) - dye]. Potentiodynamic measurements indicate that this compound acts as a slightly anodic inhibitor. Monte Carlo simulation was used to understand the studied molecules adsorption ability onto a Fe(1 1 0) surface, at the molecular level. The experimental results and theoretical calculations provided important support for the understanding of the corrosion inhibition mechanism adopted by this molecule.

Palabras clave : mild steel; inhibitor; polarization resistance; corrosion density and Monte Carlo simulation.
