CORROSION IN THE MARINE ENVIRONMENT

The author presents a discussion of the causative mechanism of corrosion as an introduction to the examination of factors which influence the corrosion of metal in the marine environment. Because all structural metals and alloys are unstable in the marine environment, the problems in materials selection and subsequent maintenance for reliable service, as stated by the author, include the assessment of the kinetics of the reactions with the environment, interpretation of these kinetics in terms which are meaningful to the designer, and the control of the kinetics to within tolerable limits by coatings and cathodic protection. As pointed out by the author, problems encountered by the corrosion engineer include the slow rate of corrosion of nearly inert alloys so that measuring the kinetics presents a serious experimental problem, as well as the non-uniformity of corrosion, thus minimizing reproducibility under laboratory conditions. Although corrosion does not usually occur in the absence of oxygen, low local concentrations of oxygen, as in crevices, lead to highly concentrated corrosion under other encouraging circumstances.
