ORTEGA-RAMIREZ, Angie Tatiana; BARRANTES-SANDOVAL, Laura Valentina; CASALLAS-MARTIN, Braian David  e  CORTES-SALAZAR, Natalia. Application of green inhibitors for corrosion control in metals. Review. Dyna rev.fac.nac.minas [online]. 2021, vol.88, n.217, pp.160-168.  Epub 18-Nov-2021. ISSN 0012-7353.  https://doi.org/10.15446/dyna.v88n217.93871.

This review article characterizes the green inhibitors applied to control corrosion in metals and maintain the safety and profitability of the production process, since the corrosive phenomenon is insoluble, but can be mitigated with time. For this article, some case studies related to corrosion problems in metals are included, such as the accident in Aloha and the explosion in Guadalajara. Subsequently, the generalities of inhibitors for corrosion control are named, and the physisorption and chemisorption processes are compared. Then, inorganic, organic, synthetic, and green inhibitors are analyzed. The latter seek to replace the synthetic ones, for example, through aloe vera and other plant materials.

Palavras-chave : corrosion; physisorption; inhibitors; chemisorption; sustainability.
