ABSTRACT:
The corrosion inhibiting activity of a coating is determined from the effect of corrosion inhibiting species released by the coating on the oxygen reduction current for a cathode placed very close to the coating. A rotating disk electrode or pumped solution flow is used to sweep the corrosion inhibiting species from the coating surface to the cathode. The oxygen reduction current is measured under conditions of oxygen diffusion control.
