使用高能微弧火花合金化技术在AZ31镁合金上用Al-Nd电极进行了合金化。研究了不同参数对合金化过程的影响以及合金化参数对电极材料的蚀除速率、质量转移规律的影响,并对电极和基材质量的变化进行了表征。结果表明,阳极和阴极的质量变化取决于工艺参数。不同参数下获得的沉积点具有相似的形貌特征,只是在尺寸上存在差别。合金化过程中同时存在电极材料向基材的转移和基材向电极材料的迁移过程。 Al-Nd electrodes were alloyed on AZ31 magnesium alloy using high-energy micro-arc-arc alloying technology. The effects of different parameters on the alloying process and the effects of alloying parameters on the electrode material removal rate and mass transfer were studied. The changes of electrode and substrate quality were also characterized. The results show that the quality of the anode and cathode changes depending on the process parameters. The deposition points obtained under different parameters have similar topographic features except for the difference in size. During the alloying process, the transfer of the electrode material to the substrate and the transfer of the substrate to the electrode material exist simultaneously.
