Sodium diethyldithiocarbamate as a highly efficient inhibitor for steel corrosion in 7.0 M H3PO4: multi-scale investigations on adsorption behavior and bonding mechanism

Key Points

• Steel corrosion is significantly reduced with sodium diethyldithiocarbamate in 7.0 M phosphoric acid, enhancing material lifespan.
• The study shows a high efficiency of the inhibitor, with corrosion rates dropping near 85% compared to untreated steel.
• Analysis focuses on adsorption behavior and bonding mechanism, elucidating how the inhibitor protects steel surfaces.
• Understanding these interactions may lead to improved protective coatings, offering manufacturers cost-effective solutions.
