Corrosion Protection Ability of Chitosan/ZnO Nanoparticles on Mild Steel in Sodium Chloride Solution

Abstract

Chloride ions in saltwater have a small ionic radius, allowing them to spread across metal surfaces and cause erosion quickly. Zinc oxide nanoparticles (ZnO NPs) incorporated with chitosan as a hybrid organic-inorganic inhibitor was used to improve corrosion protection of mild steel in sodium chloride solution.
