摘要：

Cathodic protection (CP) is a widely utilised method of corrosion prevention in aqueous systems. There is evidence that the electrochemical changes it produces on a metal surface influence the chemistry of the water and the settlement of fouling organisms. The interaction is in both directions, and fouling organisms and their products have an influence on the CP and on calcareous deposits formed on the metal in marine environments. The studies described show that, on both stainless and nonstainless steels, CP retards the development of aerobic bacterial fouling. Increasing the CP decreases the number of bacteria. Additionally, the presence of organic material affects both the current required to maintain CP and the nature of the calcareous deposits formed. The results are discussed in relation to the electrochemistry of the system.
