    Abstract

    SEAWATER IS AN AGGRESSIVE, complex fluid that affects nearly all common structural materials to some extent [1]. There are two competing processes that operate simultaneously in seawater environments: (1) the chloride ion activity, which tends to destroy the passive film, and (2) dissolved oxygen, which acts to promote and repair the passive film on metallic materials of construction [2]. Metals and alloys that develop protective films by the formation of thin metal oxides can have the formation of passive films delayed or have films destroyed by chloride ions in seawater [3].
