Sea Grant Program On Marine Corrosion : Vol. 1 Technical Summary

he efficiency and effectiveness of cathodic protection for marine service is in most instances predicated upon formation of calcareous deposits. At the same time relatively little is known about the fundamental nature of these surface films and the dependence of properties and protective character upon conditions and variables of formation. Here, three different facets of calcareous deposits were investigated: nature and properties, influences on fatique, and modeling. Based upon the data and associated analyses, conclusions have been reached regarding the properties of calcareous deposits which form under a given set of experimental conditions, and these are discussed within a perspective of present and future marine cathodic protection practice.
