Corrosion Inhibition in Magnesium by using Green Inhibitor

Abstract

Though magnesium has attractive properties in many transport applications, its use is limited because of the issue of corrosion. Corrosion rate increases under influence of pressure due to stresses acting over the metal surface. To avoid this stress induced corrosion, there is a need of an inhibitor to inhibit the corrosion. In the present work, a natural inhibitor is used as the inhibitor for preventing corrosion. The plant extract consist of active materials of plant material which has the antioxidant properties. The corrosion property of magnesium alloy in 3.5 wt% NaCl solution is analyzed. As per the study, the Moringa Oleifera leaf extract is chosen as green inhibitor. The effective inhibition of plant extract is analyzed in electrochemical workstation with varying concentration of extract.
