ANALYSIS OF MARINE CORROSION FAILURES

Failures from corrosion of materials in marine service fall into three major categories: characteristics of the material, effects of the environment, and problems associated with design. This basic framework is expanded to provide a detailed enumeration of items to be considered in attempting a rational approach to diagnosing a marine corrosion problem. Case histories devoted to instances in which certain factors were of dominant importance are discussed and illustrated to demonstrate this technique of evaluation. These case studies include an inadequate content of a critical element, dezincification, stress effects, graphitization, high velocities, uneven velocities, crevice corrosion, vibration, cavitation, cyclic stresses, micro and macro organisms, stray currents, galvanic effects, and metal salts. As outlined in this paper, the procedure for diagnosing corrosion failures has direct application to predicting corrosion failures, thereby providing a guide for the proper design and selection of materials in marine applications.
