Abstract

The influence of the composition of the anode made of various casting magnesium alloys on its electrochemical behavior in a solution of 3,5% NaClby galvanostatic electrolysis and electrochemical impedance spectroscopy has been studied. It has been established that the use of rare earth elements (REE) as alloying elements has a beneficial effect on discharge characteristics, which allows increasing the anode efficiency and discharge capacity of the VML26 alloy of the system Mg–REE–Zr compared to the Mg–Al–Zn alloy ML5p.ch. by 15 and 7 %, respectively.
