Study of Galvanized Steel Corrosion Resistance in Simulated Seawater

Abstract

The current laboratory experiments investigated the corrosion resistance of galvanized steel in artificial seawater (ASW). After the coupons were immersed in ASW for varying time durations (7 and 14 days) at room temperature, the corrosion rates based on the weight loss were determined. Following exposure to carbon steel for 7 and 14 days, corrosion rates were 0.1193mmpy and 0.1373mmpy, respectively. Methods of Scanning Electron Microscopy (SEM) and Energy Dispersive X-Ray (EDX) Analysis characterized the surface composition of their corrosion product. The visible corrosion product is hematite and lepidocrocite. This result allows us to understand the corrosion behavior of galvanized steel used in the marine environment.
