Abstract
In this study, we investigated the inhibiting effect of Dioscorea spp leaf extracts on the corrosion of mild steel in selected media using the weight loss method. The mild steel samples were pre-weighed and immersed in NaOH, NaCl and H2SO4 solutions respectively containing the leaf extracts, with the control samples immersed in solutions of the media containing no extract. The samples were allowed to stand for 672 hours, with a set of samples from each environment withdrawn at intervals of 168 hours for corrosion characterization. The results obtained from all the environments indicate that the corrosion rate increased as concentrations of Dioscorea spp increased. Results also confirmed that the extract was an effective and excellent inhibitor in the alkaline, salt, and acidic media. Conclusively it was proven that the higher concentration of Dioscorea spp leaf extracts in the media had the best inhibition characteristic on the mild steel in the selected environments. The results show good potential for application in manufacturing industries. The microstructure analysis of the various test coupons in the test media should be carried out to reveal the influence of adding the leaf extracts to the stimulated media on the grain structure distribution of the mild steel.
