Strain Electrometry and Corrosion, IV

Abstract
Measurements of the strain transients have been recorded here for several metal electrodes including copper, aluminum, zinc, nickel, silver, and iron. The magnitude of the transients as a function of the percentage strain are treated by an extension of previous theoretical results. It is found that the transients depend on the position of an electrode in the emf series and on the protective nature of the film as predicted by the theoretical considerations. In addition, several experiments have been reported concerning the effect of corrosion inhibitors and organic coatings on strain transients. Some possible theoretical interpretations are made on these preliminary results.
