ABSTRACT
To control or to kinetically inhibit corrosive process has become a major challenge for science. Because of this, researchers have tried to study the various types of interactions between the material and the environment. The use of inhibitors is one of the usual methods of corrosion protection. However, there is growing concern about the toxicity of most corrosion inhibitors. Several studies have been conducted that demonstrate the inhibitory action of plants' extracts on the corrosion of metals. This study aims to verify the inhibitory effect of Mangiferin, substance obtained from the extraction of the plant stem of Mangifera indica L, against the corrosive process in carbon steel. In this study, weight loss tests were carried out assisted by electrochemical techniques in acidic chloride. The results showed that carbon steel exposed in this medium containing Mangiferin had a reduction in mass loss process and a higher electrochemical behavior relative to the carbon steel samples exposed in the same medium in the absence of Mangiferin. These results suggest that Mangiferin shows inhibitory action on the corrosion process of carbon steel in the studied conditions.
