Effect of lanthanum, ce- rium, praseodymium on corrosion-electrochemical behavior of aluminum conductor alloy AlTi0.1 in NaCl electrolyte
https://doi.org/10.22349/1994-6716-2024-119-3-187-195
Abstract
The article presents the results of studying the effect of lanthanum, cerium and praseodymium additives (0–1.0 wt.%) as structure modifiers on the anodic behavior of the aluminum conductive alloy AlTi0.1 in the NaCl electrolyte medium. The studies were carried out using the potentiostatic method with a potential scan rate of 2 mV/s. It was found that over time, the free corrosion potential of the alloys shifts to the positive side and acquires a positive value with an increase in the modifier concentration (lanthanum, cerium, praseodymium) in the aluminum conductive alloy. The addition of lanthanum to the aluminum conductive alloy AlTi0.1 by 12–23%, cerium by 20–30% and praseodymium by 25–35% increases its corrosion resistance. An increase in the corrosion rate of the alloys with an increase in the NaCl concentration in the solution, regardless of their composition, was noted. An increase in the concentration of chloride ion in the NaCl electrolyte leads to a decrease in the potentials of free corrosion, repassivation and pitting of alloys.
