ABSTRACT:
A method for galvanostatic and potentiostatic electrochemical measurement of the rate of corrosion of an object is described wherein a working electrode, counter-electrode and reference electrode are immersed in an electrolyte and the electromotive force appearing on the cell formed by the working electrode and counter-electrode is measured and related to the reference electrode and the corrosion rate of the object is derived therefrom, the object measured being utilized as a plurality of working electrodes utilized in combination with a plurality of reference electrodes. An apparatus for performing the measurements as above described is also disclosed.
