Electrochemical and acoustic emission studies of aluminum pitting corrosion

摘要

The potentiodynamic and acoustic emission studies were carried out in a typical three-electrode electrochemical cell. The working electrode was prepared from aluminum alloy 1050A. Cyclic polarization and acoustic emission investigations of pitting corrosion were carried out simultaneously. On the basis of acoustic and potentiodynamic (cyclic polarization) investigations pitting corrosion potential was determined and compared.
