摘要

Herein, the impact of the addition of zinc on the mechanical, corrosion, and microstructural properties of Mg–3Sn–2Y alloy was examined because they can be considered in biomedical applications as potential implant materials. The mechanical and biocorrosion features of the alloy were evaluated using several tests, including analysis of the alloy’s microstructure, nanoindentation, macrohardness, tensile strength, immersion testing, and potentiodynamic polarization. These tests aimed to assess the influence of zinc’s addition on the alloy. The findings indicate that the Mg3Y2Zn3 and MgZn intermetallic phases were formed with the addition of zinc to the Mg–3Sn–2Y alloy. The incoherent Mg3Y2Zn3 intermetallic phase caused a decrease in the Mg alloy’s yield strength. However, the alloy’s nanohardness, elastic modulus, tensile strength, elongation, and corrosion resistance improved when the amount of zinc added was increased.
