Magnesium Anodes for the Cathodic Protection of Naval Vessels^★ Available to Purchase

The paper describes the results of a cooperative investigation with the Bureau of Ships on the performance of magnesium anodes in the cathodic protection of naval vessels. Coated magnesium anodes were applied in 1958 to three destroyers and their performance evaluated after two years of operation. By attaching additional coated anodes to the number of uncoated anodes required for initial protection, and having divers remove some of the coatings from time to time (when indicated by potential measurements), a service life of three years is easily obtainable from one installation. All the vessels were docked after two years and their hulls found to be in excellent condition with little or no corrosion. 5.2.2, 8.9.5
