Development of Micropogonias undulatus Scales Nanoparticulate - Reinforced In Situ Anti-Corrosion Composite Coatings

The reinforced composite coating has been proven to offer outstanding properties and increased component life span in service. Thus, its development has found a significant place in advanced engineering applications. This study aims to reinforce Zinc-Zinc Oxide composite coatings with an organic and sustainable, eco-friendly product, scales of Micropogonias undulatus (M. undulatus) anti-corrosion composite coating, for mild steel protection in service. The coating was developed via the electrolytic deposition route. The effects of the process parameter, deposition time, on the morphology and electrochemical properties were reported. While the Optical Microscope (O.M.) and Scanning Electron microscopy (S.E.M.) equipped with Energy Dispersive Spectroscopy (E.D.S.) were used for structural study, the PGSTAT 30 potentiostat linked to the electrochemical software NOVA 1.8 was used for the corrosion polarisation studies. The result showed excellent coating adhesion, substrate protection and remarkable corrosion resistant attributes with the Zn-ZnO-M. undulatus scales nanoparticulate coatings. The result also revealed that the deposition done at 25 minutes had the best and most enhanced anti-corrosion attributes.
