DEVELOPMENTS IN SHIPS' PROTECTIVE COATINGS

Marine corrosion is of considerable interest from the technical standpoint in so far as it involves most of the known classical situations of the electro‐chemical theory of corrosion, and is primarily concerned with a metal immersed in an electrolyte. In the case of ships, the area of immersed steel can well vary between 2,000 and 15,000 sq. yds. but, of course, the supply of electrolyte is unlimited.
