等离子体团是在氩的阴极放电中产生的。通过穿过烃类气体,等离子体团收集碳材料。这些等离子体团在空气气氛中与腔的内表面接触时产生金刚石单晶。当等离子体团与衬底的接触点处于惰性气氛中时,它们将其材料存款为具有石墨芯的微球。使用扫描电子显微镜和拉曼显微光谱的等离子体团沉积的微观材料的尺寸和性质进行了分析。沉积的微金刚石中的压缩残余应力在-7至-21 GPa的范围内变化。
Plasmoids are produced in the argon filamentary discharge. By going through hydrocarbon gas, the plasmoids collect carbon material. These plasmoids produce diamond single micro-crystals upon contact on the inner surface of cavity in air atmosphere. When the plasmoid's contact point on the substrate is in inert atmosphere, they deposit their material as micro-balls with a graphite core. The dimension and nature of the micro-materials deposited by the plasmoids are analysed using scanning electron microscopy and Raman microspectroscopy. The compressive residual stress in the deposited micro-diamonds varies in the range− 7 to− 21 GPa.
