Carbon Steel Corrosion in Key West and Persian Gulf Seawaters at Varying Oxygen Concentrations

摘要

Corrosion of 1020 carbon steel coupons in natural Key West and Persian Gulf seawaters was directly related to exposure conditions. Exposure conditions included the following: stagnant and sloshing, oxygenated and deoxygenated seawater, in addition to, alternating immersion and drying with oxygenated and deoxygenated sea waters. Microbial populations in the two waters fluctuated with exposure conditions. Of all of the exposure conditions, the anaerobic stagnant Key West sea water exposure produced the highest corrosion rates and sulfide levels.
