Titel
Electrochemical studies of the ECM on chromium
Abstract
The present work investigates the dissolution of chromium in various concentrated sodium nitrate solutions under near-ECM conditions. Potentiodynamic electrochemical experiments are carried out and supplemented by light microscopic diagnostic of the resultant surface topography. Under the chosen conditions the dissolution is preferred on structucal defects as dislocations and grain boundaries. An initiation of the dissolution by local corrosion attacks, e.g. pitting, cannot be observed.
