Vappro Corrosion Control Australia is pleased to present a paper, published by Dr. Nelson Cheng, from our partner, Magna International Pte Ltd, on the Inhibition of Seawater Steel Corrosion. Corrosion and degradation of materials are pernicious problems that affect infrastructure assets, industry efficiency, and environment quality. The world's diverse facilities and installations require products, methods, and techniques to protect against, mitigate, and prevent corrosion damage. Volatile corrosion inhibitors (VCIs) are one of the modern technologies used to manage corrosion for the benefit of the global economy.
The performance of a volatile corrosion inhibitor (VCI) on steel via colloid formation through its reaction with Ca and Mg ions in seawater was studied. The physical and chemical properties of seawater, with and without the VCI at different concentrations, were determined. The VCI’s effciency was assessed, and its suitability for the steel system in seawater was indicated at an optimal concentration of 0.05%.
