The Study of the Passivation Process by the Electrode Impedance Analysis

  • Chapter
Electrochemical Materials Science

Part of the book series: Comprehensive Treatise of Electrochemistry ((AN,volume 4))

Abstract

The passivity of metals has been known for a long time and an enormous amount of work has been done to characterize the nature of the passive state. An historical survey of the problem has been recently published(1) and modern contributions to the field can be found in the four International Symposia on Passivity(2–5) and in other meetings devoted to related topics.(6,7) In the course of the last decade, surface spectroscopy and optical techniques have improved our knowledge of the passive layer(8) During the same period, advanced electrochemical techniques become applicable to the solid electrode—electrolyte interface and were successfully introduced in the study of the anodic behavior of metals including the passivity phenomenon.(9) Among these techniques, the present chapter deals with ac impedance measurements,(10) extended to the subacoustic frequency range, which provide information about the kinetics of the passivation process.
