CORROSION OF STEEL IN SEAWATER DUE TO ALTERNATING CURRENT AT 50 HZ

With the increasing use of alternating current for supplying electrical energy to both ships and land installations within the coastline region, conditions have been created for the occurence of stray currents in the sea. Corrosion of the ship hull and of sea water handling machinery attributed to these currents considerably exceeds expectations. An experimental investigation of the effect of the effect of an laternating electric field on the rate of steel corrosion in synthetic sea water is described. Corrosion rate has been expressed in terms of the metal potential and of dissolved iron in the electrolyte and related to currentdensity. The results indicate that a.c. current of higher densities (0.25--2.0 A/dm squared has a considerable influence on the corrosion rate of steel in seawater. Order from: BSRA as No. 47,357.
