Anodic protection, first demonstrated by Edeleanu in 1954,1  has been widely applied as an industrial corrosion control method.2-5  Although the major advantages and limitations of this technique have been discussed in considerable detail,6-8  the problems associated with the protection of crevices have been largely ignored. Crevice effects have probably not been troublesome in the past, since anodic protection has been generally restricted to storage tanks.2-5  However, in more complex plant structures, crevices and other narrow electrolyte paths are invariably present. Examples include: threaded pipe sections, bolt and rivet holes and flanges. Also, unintentional crevices associated with porous welds and other surface defects are more likely in large systems.
