The corrosion product morphology on a zinc alloy, exposed in a zinc steel couple in sea water is investigated as a function of pressure. The results consist of corrosion data obtained from laboratory and ocean cells and data obtained from a scanning electron microscope. The corrosion products are observed to take two distinct microscopic forms. A porous sheet zinc oxide structure is observed on the samples exposed in stagnant sea water. A cloudy, somewhat less porous oxide is observed on the zinc samples exposed in the ocean.
