Electrochemical Behavior of Galvanized Steel in a Calcium Hydroxide-Saturated Solution. A Quantitative Assessment of Corrosion Rate.

Abstract

An electrochemical study has been carried out involving immersion of galvanized steel in a Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://mathoid.scipedia.com/localhost/v1/":): Ca(OH)_2-

saturated solution with and without chloride additions. Results show that galvanized steel corrodes steadily during the first few days; after approximately a week, however, it becomes passive, the passivity being perfectly stable both in the presence and absence of chlorides for the entire test period which lasted for more than 60 days' exposure.
