Finding good protective coatings that hold up to harsh marine environments has always been an important goal to US Navy. Because of the large quantity of steel used in ship construction and repair, and the tremendous amount of money spent annually for corrosion control, it is imperative that good protective coatings are found to protect topside systems. To achieve this objective, a long term study was conducted to evaluate the performance of some aluminum pigmented coatings on carbon steel m various marine environments1. An attempt is made to correlate the results obtained from the field and laboratory tests. Several coatings appear to be promising candidates for harsh marine usage for surface combatants.
