Abstract
The corrosion-electrochemical behavior of the lithium-doped aluminum conductor alloy AlV0.1 in a NaCl solution was studied using the potentiostatic method at a potential sweep rate of 2 mV/s. The dependence of the change in the free corrosion potential on time for the original AlV0.1 alloy and alloys with lithium show a shift of the potential towards positive values. It is noted that an increase in lithium concentration leads to a shift in the potentials of free corrosion, repassivation and pitting to the region of positive values.
With an increase in the concentration of chloride ion in the NaCl solution, a shift to the negative region is observed in the values of the electrochemical potentials of the aluminum conductor alloy AlV0.1 with lithium additives. An increase in the concentration of chloride ion contributes to an increase in the corrosion rate of alloys, regardless of their composition. It has been shown that the addition of lithium reduces the corrosion rate of the aluminum conductor alloy AlV0.1 by 8…13% in a NaCl solution.
