Abstract

Particle synthesis has seen significant advances in current trends. However, the synthesis of metal particles without oxidation is a challenge for researchers. The current study presents a straightforward, convenient, and convincing approach for manufacturing copper (Cu) particles free of surface oxide. The die-sink Electrical Discharge Machine (EDM) of copper alloys with oleic acid resulted in the formation of Cu particles with diameters between 10 to 20 µm. X-ray diffraction (XRD) was used for particle examination after cleaning and sonication with distilled water. Cu particles with oleic acid coating retained a Cu phase without oxidation after synthesis. Transmission electron microscopy (TEM) and scanning electron microscopy (SEM) were used to determine the size and morphology of generated particles. Fourier transforms infrared (FT-IR) analysis revealed the oleic acid-coated Cu surface bonded with an oxygen atom. Also, the agglomeration and change of size involving Cu particles with increasing voltages in the pulse supply in EDM were reported.

摘要

在当前趋势下，颗粒合成取得了显著进展。然而，无氧化金属颗粒的合成对研究人员来说是一项挑战。当前的研究提出了一种直接、便捷且有说服力的方法来制造无表面氧化物的铜（Cu）颗粒。用油酸对铜合金进行电火花加工（EDM）沉模，形成了直径在10至20微米之间的铜颗粒。在用蒸馏水清洗和超声处理后，使用X射线衍射（XRD）对颗粒进行检测。合成后，带有油酸涂层的铜颗粒保留了无氧化的铜相。使用透射电子显微镜（TEM）和扫描电子显微镜（SEM）来确定所生成颗粒的尺寸和形态。傅里叶变换红外（FT-IR）分析表明，油酸包覆的铜表面与一个氧原子键合。此外，还报道了在电火花加工中，随着脉冲电源电压升高，铜颗粒的团聚和尺寸变化情况。
