THE ASSESSMENT OF INHIBITIVE EFFECT OF CYMBOPOGON CITRATUS ON MARINE CORROSION OF MILD STEEL
Numerous extensive efforts have been done to acquire the applicable green corrosion inhibitors in order to decrease the corrosion rate of the materials. The corrosion inhibition of mild steel is vital for technology due to the increased industrial applications of these materials. In this report, the inhibitive action of Cymbopogon Citratus on the marine corrosion of mild steel was evaluated. The inhibition efficiency was calculated using weight loss measurement method, electrochemical measurement and inhibitor mechanism analysis. It was found that, Cymbopogon Citratus exhibited a very good performance as a green corrosion inhibitor for mild steel corrosion in seawater. All the experimental methods used for this project show that the presence of Cymbopogon Citratus in the seawater significantly decreases the corrosion rates and further decreasing the corrosion rates as the concentration of Cymbopogon Citratus increases. To sum it up, the inhibition efficiency increases with an increase in Cymbopogon Citratus concentration.
