| 摘 要： | 研究了Zn-1.2Cu-1.2Mg-xGd（x=0，0.1，0.25，0.5，质量分数，%）锌合金微观组织、在模拟体液中的腐蚀行为和力学性能。结果表明，锌合金组织主要由Zn固溶体和Mg2Zn11金属间化合物组成。当Gd添加量为0.5%时，形成了GdZn12化合物。锌合金的硬度随Gd添加量的增加而增加，在0.5% Gd添加量时，硬度达到最大值为1530 MPa。在0.25% Gd添加量时锌合金具有高的抗拉伸强度，而在0.1% Gd添加量时锌合金具有最低的腐蚀速率。

| Abstract: | The microstructure, immersion corrosion behaviour in simulated body fluid and mechanical properties of Zn-1.2Cu-1.2Mg-xGd (x=0, 0.1, 0.25, 0.5, wt%) alloys were studied. The results show that the microstructure of zinc alloy is mainly composed of Zn solid solution and Mg2Zn11 intermetallic compound. When Gd addition content is 0.5wt%, the GdZn12 intermetallic compound appears. The microhardness of zinc alloy increases with the increase of Gd addition content, and when the addition content of Gd is 0.5wt%, the microhardness reaches maximum, 1530 MPa. The tensile strength increases first and decreases afterwards, and when the Gd addition content is 0.25wt%, the zinc alloy has high tensile strength. Zinc alloy with 0.1wt% Gd addition content has the lowest corrosion rate. |
