The article is devoted to the study of the anodic behavior of the Zn0.5Al alloy doped with erbium. An acidic medium (HCl) was chosen as the corrosion medium for the study. By adding erbium (0.01÷1.0%) to the initial alloy, alloy samples of different compositions were obtained. The anodic behavior of these alloys was studied using the potentiostatical method. With increasing HCl concentration (0.001÷0.1N) in an acidic environment, the corrosion rate of the alloys increases. When alloying the Zn0.5Al alloy with erbium, its anticorrosive properties change. Erbium additives (0.01÷0.1%) reduce the corrosion rate of the Zn0.5Al alloy by 2–3 times.

Keywords: Zn0.5Al alloy, erbium, potentiostatic method, acidic environment, corrosion potentials, corrosion rate, anodic behavior.
