Selected nanostmcture coatings on steel have been characterized in ASTM seawater using polarization resistance measurement and Electrochemical Impedance Spectroscopy (EIS) techniques. Samples of nanocoatings were also tested by exposing them to an accelerated corrosion cabinet test and to the natural marine environment. Results of laboratory testing and exposure to the natural marine environment are
correlated along with supporting evidence of metallographs.
