Exploring Corrosion Protection Potential of Sustainable and Green Morus alba 'Pendula' Fruit Extracts

With climate change, corrosion is becoming more and more important. This phenomenon reduces the strength of metals and causes both huge damage and environmental pollution. It can be said that among all the methods to prevent corrosion, the use of chemical corrosion inhibitors is very common. But they cause environmental pollution because many of the raw materials used to prepare these inhibitors are toxic. On the other hand, many of them cause the release of heavy metals into the environment. Therefore, today, researchers are evaluating the use of plant extracts as a corrosion inhibitor. These inhibitors are known as green corrosion inhibitors (GCI). In this study, an attempt was made to evaluate the corrosion potential of the ethanolic extract of Morus alba 'Pendula' fruit on mild steel (MS) in salt solution. For this purpose, electrochemical impedance spectroscopy (EIS) testing was used. The evaluation results showed that this extract improves corrosion resistance and can be used and evaluated in protective coatings in the future.
