Natural liquid-extract of Morinda Citrifolia as corrosion inhibitor for steels (AISI-1045) exposed to acidic environments of HCl. Both the organic and inorganic compounds commonly used in the industry to inhibit the corrosion process of metals and its alloys are mostly composed by highly toxic chemicals, in addition to being more expensive. In this research sugar-components derived from the Morinda Citrifolia (MC) leaves have been extracted in aqueous solution to perform a natural inhibitor capable to control de corrosion damage, which can replace the traditional inhibitors, being environmentally friendly. The experimental results indicate that this compound has shown excellent performance as corrosion inhibitor, reaching inhibition efficiency (EI), values up to 90% at inhibitor concentrations ranging 0.8 to 2 g•L−1 and immersion times of about 1 to 4 h. It has been found that the inhibition process takes place by the adsorption of the molecules on the surface of the metal (AISI 1045), by a physisorption mechanism. proyecto de investigación 3817/2014/CID (UAEM-Secretaria de Investigación y Estudios Avanzados). |
