Abstract

"The negative difference effect exhibited by magnesium while anodically dissolving in saline solutions has been attributed in part by Kokoulina and Kabanov to the expulsion of univalent magnesium ions 1, 2. Recent experimenters have discounted the concept of the anodic expulsion of uncommon valency ions and have explained both the positive and negative difference effects observed for magnesium in dilute acids on the basis of anodic polarization, film disruption, and disintegration of the magnesium anode, i.e. "chunk effect"3, 4.

The purpose of this present investigation was to study the difference effect for deformed magnesium in a dilute acid. If the disintegration of the electrode is partly responsible for the difference effect, stressing or deforming the metal might affect the degree of disintegration so as to cause a change in the transition point of the positive to the negative difference effect. Additionally, this study would provide further data for determining whether or not the disintegration was a function of the history of the metal fabrication and subsequent treatment"--Introduction, p. 1
