MODEL TESTS OF ELECTROCHEMICAL PROTECTION AGAINST CORROSION OF SHIPS' HULLS AND DETERMINATION OF EFFECT OF PROPELLERS ON THE CONDITIONS OF FUNCTIONING OF THIS PROTECTION,
Abstract
This article discusses the methodology of model tests of electrochemical protection and the nature of distribution of potential over the hull of a ship with different versions of protection and cathode shields. The expediency of using these devices in combination with lacquer paint coatings is demonstrated. On the basis of theoretical and experimental investigations, recommendations are made for appraisal of the effect of the propeller during design of an electrochemical protection system for the submerged parts of ships' hulls.New methods of shielding, sizes and distances of anodes or protectors, the effect of lacquer paint coatings, ship's propeller, etc, were quickly and easily checked during model tests which were done as part of an overall research program. Propellers are made of copper alloys or stainless steels and, in the two electrode system 'hull-propeller', they are a cathode and exert a vital influence on the corrosion of the outside layer of the stern section of the hull, as well as on conditions for electrochemical shielding.
