Abstract : Methods have been developed to utilize the standard 1/8-inch diameter tensile bar and stressing fixture for conductivity studies to establish the cathodic protection criterion for both unstressed and stressed specimens. An anodic polarization technique that shows promise for evaluating the interaction between metallurgical structure and electrolyte has been developed. There are two important factors in the technique: (1) an anodic pretreatment to develop active, localized attack characteristic of the metallurgical structure and (2) a rapid scanning rate to evaluate this localized attack before it is stifled by film repair.
