Corrosion Control of Pilings in Seawater: Buzzards Bay.

Abstract

This report assesses (1) the rate of corrosion of steel piles with and without cathodic protection after 5 years in seawater at Buzzards Bay, MA, and (2) the performance of the piles' coatings. One row of pilings was pulled out and inspected. The U.S. Army Construction Engineering Research Laboratory then established ratings for the following coatings: organic, organic over metal filled, organic over metal filled with cathodic protection, metallic, and organic over metallic. It is concluded that (1) sacrificial anodes of zinc and aluminum effectively reduced the corrosion rate of bare carbon steel (ASTM A36) piles in the immersed zone from 3.4 mils/yr to zero, and (2) the coating performing best was coat tar epoxy over zinc-rich primer.
