Abstract

The experimental study results of synthesizing molybdenum carbide in a plasma of a direct-current arc discharge by the vacuum-free method are presented. The influence of the current amplitude of the discharge circuit on the phase composition of the synthesis product is established. The synthesis product contains a microdimensional component and a nanosized one. The scanning electron microscopy (SEM) and X-ray diffractometry methods identified carbon fibers with a graphite structure and modified fibers containing graphite and molybdenum carbide as part of the microsized component. The nanoscale component contains clusters of particles that are a graphite matrix in which molybdenum carbide particles are immersed.

基于石墨和碳化钼的材料电弧放电合成

摘要

提出了利用无真空法在直流电弧放电等离子体中合成碳化钼的实验研究结果。建立了放电电路的电流幅度对合成产物的相组成的影响。合成产物包含微观成分和纳米成分。扫描电子显微镜（SEM）和X射线衍射法确定了具有石墨结构的碳纤维以及含有石墨和碳化钼作为微细成分的一部分的改性纤维。纳米级组分包含作为石墨基质的颗粒簇，碳化钼颗粒被浸入其中。
