• Abstract:
  Evaluation of the electrochemical characteristics of the AE21 magnesium alloy is presented in the article. The surfaces of tested alloys were treated by grinding and grinding followed by sodium bicarbonate shot peening. The specimens were evaluated by electrochemical impedance spectroscopy method in combination with exposure tests in 0.1 NaCl solution. The exposition times were from 5 minutes to 168 hours. The measured data were analyzed using equivalent circuits and polarization resistances of the various corrosion systems were determined. Results of the electrochemical measurements are complemented by metallographically evaluation of the tested alloy.
