ELECTROCHEMICAL BEHAVIOR OF WEATHERING STEEL WITH HIGH Cr CONTENT
|
Abstract:
In order to study the influence of high Cr content on corrosion resistance of weathering steel,electrochemical tests were carried out.Firstly,polarization curves were obtained by potentiodynamic scanning method.The results showed that E0(free corrosion potential)increased and corrosion rate decreased due to increasing the mass fraction of Cr.According to the analysis of EIS the weathering steel with high Cr content was covered by a more compact and effective corrosion product film with higher resistance to ...
