Effect of stress on electrolytic solution potential McDonnell, Basil

Abstract

Uni-directional stresses have been applied, to copper wires, and the potential difference between such wires and unstressed wires determined in various electrolytes. The potential differences have been determined both by a galvanometer method and potentiometrically. The latter method gave more consistent results and is thought to eliminate some of the possibilities of polarization. Some correlation has been found between the amount of applied stress and the potential difference observed, and thermodynamic arguments have been advanced to explain such results, at least qualitatively. A correlation of these same results with time has led to the conclusion that the potential difference is essentially due to a surface effect.
