Abstract
A system which allows electrochemical studies to be conducted in relatively uncontaminated aqueous solutions at 289°C, using a reference electrode which permits potentials to be referred to the standard hydrogen electrode scale, is described. Current‐potential curves for Type 304 stainless steel, Inconel 600, and other iron and nickel‐base alloys containing less than 14% Cr are presented. It is found that passivation in dilute is more difficult at 289°C than at 25°C because of the faster attack by the acid at the high temperature.Keywords
