Anodic behavior of gallium doped Zn55Al alloy in acid, neutral and alkaline environments
https://doi.org/10.22349/1994-6716-2022-111-3-79-84
Abstract
The paper presents results of potentiostatical and potentiodynamical research of anode behaviour of gallium-doped Zn55Al alloy in acid, neutral and alkaline environments of electrolytes HCl, NaCl and NaOH, at various pH values. Gallium additives (0.01-1.0 wt%) lead to displacement of corrosion electrochemical potential, pitting formation and repassivity to positive values. The results indicate a decrease in the corrosion rate of gallium doped alloys by 2-3 times compared to the base alloy. Such dependence is observed in all investigated corrosion environments.
