Coatings and Cathodic Protection of Pilings in Seawater: Results of 5-Year Exposure.

Abstract

This report presents the results of the inspection of test pilings extracted after 5 years of exposure to seawater at LaCosta Island, FL. The effectiveness of various coating systems and sacrificial anodes in preventing corrosion of H- and steel pipe pilings in seawater is assessed. Six of the coating systems were found to perform excellently, as was a coating/cathodic protection combination. Sacrificial anodes of zinc and aluminum were also found to effectively reduce corrosion in the immersed zone. The study also confirmed that use of the cathodic protection index and polarization behavior is an effective nondestructive testing technique for monitoring corrosion of steel immersed in seawater.
