Potentiodynamic stadies of corrosion-electrochemical behavior of AMG0.2 alloy allocated scandium, yttrium and lanthanum in the medium of electrolyte NaCl

The corrosion-electrochemical behavior of the AMg0.2-Sc, (Y, La) alloys in the NaCl electrolyte is investigated by the potentiostatic method in the potentiodynamic mode at a potential sweep rate of 2 mV/s. It is shown that alloying with Sc, Y and La reduces the corrosion rate of the initial alloy by approximately 1.5 -2 times, depending on the concentration of the electrolyte. Reducing the rate of corrosion is associated with the process of passivation of alloys.
