以Mg-33%Zn(质量分数)合金为阴极,石墨为阳极,在740℃的 KCl-SrCl2熔盐体系中进行液态阴极合金化法电解,并在670℃浇铸反应液制备 Mg-Zn-Sr 合金。浇铸产物车削加工后取样,分别进行 X射线荧光分析(XRF)、金相分析(OM)、扫描电镜形貌分析(SEM)、能谱分析(EDS)及 X 射线衍射分析(XRD),并与阴极合金组织进行比较。结果表明,实验成功制备了 Mg-Zn-Sr 三元合金,Sr 的质量分数为1.6279%,且 Sr 细化了阴极合金的组织。对比熔炼制备的 Mg-Zn-Sr 合金组织,电解的 Sr 具有更好的细化效果。

Using Mg-33wt% Zn alloys as the cathode,graphite as anode,to conduct electrolysis by liquid cathode alloying in KCl-SrCl2 melts at 740 ℃,and casting the reaction liquid at 670 ℃ to prepare the Mg-Zn-Sr alloys. After cutting the casting product into standard specimens,the samples were analyzed by means of X-ray fluores-cence,optical micrograph (OM),scanning electron microscopy (SEM),energy dispersive spectrometry(EDS) and X-ray diffraction(XRD),and compared with the cathode alloys.The results show that the reaction prepared Mg-Zn-Sr ternary alloys successfully,the mass fraction of Sr was 1.6279%,and Sr refine the cathode alloys. Compared to the microstructures of molten Mg-Zn-Sr alloys,and found that the electrolytic Sr can refine micro-structures better.
