FUNDAMENTALS OF CATHODIC PROTECTION FOR MARINE SERVICE

This report at first discusses in fundamental terms the nature of galvanic corrosion and electron flow, and then examines the behavior of dissimilar metals in a sea water electrolyte, and of how applied currents can protect steel surfaces. With this background, the report then details the design, application and maintenance of both galvanic anode systems and impressed current systems, covering types of anodes and shields, method of attachment, power supplies and current requirements, monitoring and precaution to be taken during docking.
