Abstract A high-throughput shaker-pot spark erosion process was used to synthesize a spherical polydisperse 316L stainless steel nanopowder. Capacitance and target morphology of the shaker-pot spark erosion process were evaluated to optimize powder production. Nanopowders were assessed using X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission scanning electron microscopy (TSEM), dynamic light scattering (DLS), and a new multispectral advanced nanoparticle tracking analysis (MANTA) technique. It was found that the chosen spark erosion dielectric, as well as capacitance, heavily impact the submicron particle size distribution and overall production rate. The distribution of the particles obtained was shown to be a wide range bimodal distribution with a small mode near 150 nm and a large mode near 50 μm. Spark energy and time were shown to have a strong correlation with the chosen dielectric and capacitance parameters.

电火花腐蚀作为生产双峰纳米结构 316L 不锈钢粉末的高通量方法

摘要 采用高通量摇床-罐式电火花腐蚀工艺合成球形多分散316L不锈钢纳米粉体。评估了振动罐火花腐蚀工艺的电容和目标形态，以优化粉末生产。使用 X 射线衍射 (XRD)、扫描电子显微镜 (SEM)、透射扫描电子显微镜 (TSEM)、动态光散射 (DLS) 和新的多光谱高级纳米粒子跟踪分析 (MANTA) 技术评估纳米粉末。发现所选择的电火花腐蚀电介质以及电容会严重影响亚微米粒度分布和整体生产率。所得颗粒的分布显示为宽范围的双峰分布，具有接近 150 nm 的小模式和接近 50 μm 的大模式。
