CONTRIBUTION TO THE STUDY OF SEVERAL VARIABLES WHICH AFFECT THE CATHODIC PROTECTION OF STEEL,

Abstract

The effect of a series of variables is studied which affect the cathodic protection of steel in saline solutions. In sea water the cathodic surface becomes modified with time by the formation of a magnesium-calcium deposit on the metal, thus affecting the protective current which is appreciably reduced. By studying the effects temperature, aeration, movement and current density on the formation and characteristics of such deposits, new information is obtained on the factors which govern their production. An expression which relates the distinct variables with the chemical composition of the magnesium-calcium layer is theoretically deduced. (Author)
