Abstract: In order to balance the mechanical properties and degradation rate of zinc-based alloys, the Zn-xCu-ySr(x=2, 3, 5;y=0.1, 0.3) ternary alloy was designed and cast, and the effects of different Cu and Sr contents on the microstructure and properties of as-cast Zn-Cu-Sr alloy were investigated. The results showed that the microstructure of Zn-xCu-ySr alloy consisted of zinc matrix, ε-CuZn5 and SrZn13 intermetallic compounds. When the contents of Cu and Sr were 5.0wt% and 0.3wt%, the tensile strength and hardness of zinc-based alloy reached the highest, which were 165.3 MPa and 85.5HB, respectively. The corrosion mode of Zn-xCu-ySr alloy was uniform corrosion. When the contents of Cu and Sr were 2.0wt% and 0.1wt%, respectively, the corrosion resistance of Zn-2Cu-0.1Sr was the best, the corrosion rate in static immersion test was the slowest, which was about 0.044 mm/a. And the corrosion current density and corrosion rate in potentiodynamic polarization test(PDP) were the smallest, which were 15.10 μA/cm2 and 0.078 mm/a, separately.
