Ⅲ. Advanced Electrochemical Methods for Corrosion Study―Detection of Permeated Hydrogen by Electrochemically―

Abstract

The diffusible hydrogen in the metals plays an important role in the delayed failure and hydrogen embrittlement. Therefore, the focus is on detection of hydrogen permeated through the steel in this article. The detection of permeated hydrogen electrochemically (Devanathan-Stachurski double cell) is explained in detail. It also demonstrated that the application of micro-electrochemical cell to detected permeated hydrogen during wet/dry corrosion of scratch formed zinc coated steel.
