摘要：

The results of the experimental study of the effect of sodium on the anodic behavior of AlTi0.1 aluminum conductor alloy in a medium of NaCl electrolyte are presented. Studies have been carried out using the potentiostatic method in the potentiodynamic mode at a potential sweep rate of 2 mV/s. It has been shown that sodium modification of the AlTi0.1 aluminum conductor alloy contributes to the shift of the potentials of free corrosion, pitting formation, and repassivation to the positive range of values. The corrosion rate of AlTi0.1 aluminum conductor alloy when modified with 0.01-0.5 wt % sodium is reduced by 10-20%. Depending on the concentration of chloride ions in the NaCl electrolyte, the corrosion rate of the alloys increased and the electrochemical potentials shifted to the region of negative values.
