摘要:

采用传统重力铸造法制备了Mg-3Zn-1Y-xZr (x=0，0.2，0.4，0.6) 合金，并通过光学显微镜 (OM)、扫描电镜 (SEM)、失重和电化学实验研究了Zr含量对Mg-3Zn-1Y显微组织和腐蚀行为的影响。结果表明：Mg-3Zn-1Y主要由α-Mg基质和Mg₃YZn₆(I) 相组成，Zr的加入没有改变第二相的类型。Zr能显著细化晶粒，优化组织结构，提升合金耐腐蚀性。同时，Zr能提升合金基体腐蚀电位，减小腐蚀电流密度，抑制合金腐蚀。失重结果表明，Mg-3Zn-1Y-0.6Zr具有最佳的耐腐蚀性能，达到 (0.325±0.042) mm/a。

关键词 ： Zr, 显微组织, 腐蚀行为, 晶粒细化, 失重

Abstract：

Mg-3Zn-1Y-xZr (x=0, 0.2, 0.4, 0.6) alloys are prepared by traditional gravity casting. The influence of Zr amount on the microstructure and corrosion behavior of Mg-3Zn-1Y alloys is systematically investigated via optical microscope (OM), scanning electron microscope (SEM), mass loss testing and electrochemical testing. Results show that the Mg-3Zn-1Y alloy is mainly composed of α-Mg matrix and Mg₃YZn₆ (I) phase. The addition of Zr does not change the type of the second phase, while can remarkably refine the grains by increasing nucleation rate, optimize the structure and improve the corrosion resistance of Mg-3Zn-1Y alloys. Meanwhile, the addition of Zr can increase the corrosion potential of alloy substrate, reduce the corrosion current density, thereby decreasing the tendency of corrosion and inhibiting the corrosion. The mass loss results indicate that the Mg-3Zn-1Y-0.6Zr alloy has the best corrosion resistance with corrosion rate of (0.325±0.042) mm/a.

Key words： Zr microstructure corrosion behavior grain refinement mass loss
