Transactions of The Electrochemical Society, 1942 If the corrosion is electrochemical, it may be concluded from this work that: 1. In order that protection may be complete, the potential of the cathode areas must be polarized to a potential equal to or more anodic than the open circuit potential of the anodes. 2.
