  • The Effects of Saltwater on Metals Sciencing

    Apr 27 2018 · One form of corrosion that occurs when metal and saltwater get together is called electrochemical corrosion. Metal ions dissolve in water and saltwater conducts electricity and contains ions which attract ions from other compounds. During electrochemical corrosion electrons from other compounds are attracted to the metallic ions.

    Abstract. While NaNO 2 addition can greatly inhibit the corrosion of carbon steel and ductile cast iron in order to improve the similar corrosion resistance ca. 100 times more NaNO 2 addition is needed for ductile cast iron compared to carbon steel. A corrosion and inhibition mechanism is proposed whereby ion is added to oxidize. The ion can be reduced to nitrogen compounds and these
