Natural products were used for the protection of MS materials from corrosion. A percentage inhibition efficiency of inhibitors was carried out by various methods like WL and electrochemical methods such as PDP and EIS. Nature of films produce on metal surface was studied by FT-IR, UV-Visible spectroscopy, EDX and SEM methods. Physisorption of extract is best described by the Langmuir adsorption model. In this review paper, research works produced over the past background on the corrosion inhibition studies of MS in NaOH and KOH solutions by using a natural products as green inhibitors were presented.
