The employment of environmentally friendly alternatives is gaining prominence in the sphere of engineering and research, to the development of the idea of green chemistry and sustainable development. Because of their natural and biological origin, plant extracts are attracting a lot of attention in modern corrosion inhibition systems (MCISs), which involve the retardation of corrosion metallic corrosion inhibition through proper designing, materials selection, and implementation of corrosion inhibitors. According to a review of the literature, a number of papers describing their anticorrosion action for metals and alloys have been published. Plant extracts include complex phytochemicals with electron-rich sites that interact strongly with metallic surfaces. These phytochemicals are frequently conjugated with a wide range of multiple bonds and polar functional groups. The purpose of this review article is to summaries a collection of recent important publications on plant extracts as corrosion inhibitors. Metals have traditionally been protected against corrosion by natural extracts. To test the efficacy of these extracts as corrosion inhibitors, electrochemical assays such as potentiodynamic polarisation, electrochemical impedance spectroscopy, and weight loss measurement are often employed. |
