以AZ31镁合金表面制备Al-Zn熔渗层为研究对象,利用高能研磨机进行高能研磨试验,研究了不同时间对镁合金表面熔渗层的影响。利用扫描仪、扫描电镜(SEM)观察熔渗层表面、界面形貌,并对熔渗层界面进行能谱分析(EDS);利用X射线衍射仪(XRD)系统分析熔渗层相组成;用动电位极化曲线分析熔渗层的耐蚀性。结果表明,随着时间延长,镁合金表面熔渗层厚度增加,同时耐蚀性能得到提高。
The Al-Zn infiltration layer was prepared on the surface of AZ31 magnesium alloy as the research object. The high-energy grinding test was carried out by using a high-energy grinder to study the influence of different time on the infiltration layer on the surface of magnesium alloy. The infiltration layer surface and interface morphology were observed by scanning and scanning electron microscope (SEM), and EDS was performed on the infiltration layer interface. The phase composition of infiltration layer was analyzed by X-ray diffraction (XRD) Potentiodynamic Polarization Analysis of Corrosion Resistance of Infiltration Layer. The results show that with the extension of time, the thickness of infiltration layer on the surface of magnesium alloy increases, and the corrosion resistance is improved.
