Abstract

Corrosion is the gradual destruction of materials (usually metals) by chemical reaction with its environment whose impact is felt in economics, safety and environmental damages. To protect metal and alloys from corrosion, approaches such as isolating the structure from aggressive media (using coatings or film forming chemicals) or compensating for the loss of electrons from the corroded structure should be implemented. In recent times, research has been in the field of corrosion inhibitors using cheap effective materials of low or non-negative environmental impact to replace environmentally hazardous compounds. Corrosion inhibitors may include organic (green) or inorganic (synthetic) compounds that adsorb on the metallic structure to isolate it from its surrounding media in order to stop or slow down the rate of oxidation. In this research, the mild steel of geometric area of 1cm2 embedded in Moringa Oleifara resins was used as the working electrode; platinum electrode was used as counter electrode and saturated silver/silver chloride was used as reference electrode, while caustic soda was used as the electrolyte. This was done at different proportions of Moringa Oleifara extract to Caustic Soda. In conclusion, the ethanol extract of Moringa Oleifara leaves could slow down the corrosion rate of mild steel in caustic soda solution. Meanwhile, 7% of Moringa Oleifara leaves tends to be the most appropriate proportion to be used. Therefore, Moringa Oleifara leaves extract can serve as a good(green) inhibitor for preventing or slowing down the rate corrosion of mild steel.
