Abstract
In this paper an investigation is described of the effect of superimposed a.c. on the corrosion of anodically polarised platinum in sodium chloride solutions, using capacitance and resistance measurements to study the formation and destruction of oxide films on the electrode surfaces. Increased corrosion was found when up to 30 per cent a.c. was superimposed on d.c. The importance of reducing the a.c. component in rectified currents used in cathodic protection and electrolytic processes is shown.
