Abstract

The most important problem that threatens metal structures is corrosion. Corrosion is a slow process, although it is very fast in environments such as industrial estates or the ocean. This phenomenon causes huge environmental pollution. Many chemical corrosion inhibitors are very toxic, but they are still used. Therefore, researchers are looking for green inhibitors, many of which are prepared from plant extracts. In this study, Portulaca oleracea extracts were prepared using two solvents (ethanol and water), and their corrosion inhibition potential on mild steel (MS) in salt solution was evaluated. For this purpose, electrochemical impedance spectroscopy (EIS) was used for electrochemical tests. The results showed that the role of the solvent is effective in preparing the extract, and ethanol is a more suitable solvent for preparing the inhibitor from Portulaca oleracea. Also, the extract prepared with ethanol showed an inhibition efficiency of 64%. According to the results of this study, it can be said that this extract can be investigated in protective coatings.
