摘要 采用X射线衍射仪、扫描电镜、极化曲线及电化学阻抗谱研究微量Zn对AM60-2%RE镁合金显微组织及耐腐蚀性能的影响。结果表明:合金中添加的微量Zn主要固溶于基体中,未与合金中其他元素形成中间相;但Al11RE3相数量显著增加,沿晶界呈断续状态分布。随着Zn含量的提高,合金的腐蚀电流密度显著降低,电荷转移电阻增加,腐蚀产物的致密性提高,合金耐蚀性能得到明显地改善。添加0.8%Zn的合金的腐蚀速率为0.405mg·cm-2·d-1,降低至Zn含量为0.2%时的36%。

Abstract:The microstructure and corrosion properties of AM60-2%RE magnesium alloys with the addition of trace Zn were investigated by X-ray diffractometer(XRD), scanning electron microscope(SEM), polarization curve and electrochemical impedance spectroscopy. The results show that the Zn element added is mainly solution distributed in the matrix, without forming new intermediate phase with the other elements; while, the amount of phase Al11RE3 increases obviously, and is distributed intermittently on the grain boundary. With the increase of Zn content, the corrosion current density of the alloys is reduced, the charge transfer resistance increases and the compactness of corrosion products is improved, leading to obviously improved corrosion resistance. The corrosion rate is 0.405mg·cm-2·d-1 for the alloy with 0.8% Zn addition, which is lowered to 36% that of the alloy with 0.2% Zn addition.
