Original 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 shotpeening. 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 analysed using equivalent circuits and polarization resistances of the various corrosion systems were determined. Results of the electrochemical measurements are complemented by metallographical evaluation of the tested alloy.

V článku je uvedeno hodnocení elektrochemických vlastností hořčíkové slitiny AE21. Povrch vzorků byl broušen a následně kuličkován hydogeuhličitanem sodným. Vzorky byly hodnoceny metodou elektrochemické impedanční spektroskopie v kombinaci s expozičními testy v 0,1M roztoku NaCl. Expoziční časy se pohybovaly v rozmezí 5 minut až 168 hodin. Výsledky elektrochemických testů jsou doplněny metalografickým hodnocením experimentálního materiálu.
