Electrochemical Study of External Corrosion of Three API Steels Exposed to Seawater and Sediment from Seabed of the Gulf of México

An electrochemical study of three API steels: X52, X65, and X80, exposed to seawater and sediment from seabed is presented. Two seabed samples were collected at 60 meters depth near a platform (seabed A) and at a distance of 500 m (seabed B) from the same platform of the Sonda of Campeche, Mexico. In both samples, the seawater and sediment were separated in order to characterize their corrosiveness in an electrochemical cell of 100 mL. The...
