Transient Voltage Changes Produced in Corroding Metals and Alloys

Abstract

Abstract : The formation of 'hollow whiskers' by the action of slightly acidified potassium ferricyanide and ferrocyanide solutions on metals and alloys appeared to indicate that corroding metals produce bursts of metal ions from various point anodes. Since these bursts of ions appeared to be of a sporadic nature, it seemed possible that there might be transient fluctuations of the electrical charge on the metal. The communication reports on the detection of such fluctuations in electrical charge.
