Аннотация

We have proposed a composition of a new alloy based on zinc alloy TsAM 4-1, prepared from Ts3 crude zinc: TsAMSv 4-1-2.5. The alloy has been studied potentiostatically in potentiodynamic mode in NaCl electrolyte at a potential sweep rate of 2 mV/s. We have assessed the effect of vanadium additions on the electrochemical corrosion behavior of zinc alloy TsAMSv 4-1-2.5 in NaCl electrolyte. The results demonstrate that alloying with vanadium shifts the free corrosion, pitting, and repassivation potentials of the alloys to positive values. With increasing chloride ion concentration, the corrosion rate of the alloys rises, independent of their composition. The addition of vanadium to alloy TsAMSv 4-1-2.5 reduces its corrosion rate in NaCl electrolyte by 15–20%, which in turn ensures a decrease in protective layer thickness and makes it possible to save at least 10% of the metal.
