Abstract:
"NbS2 and TaS2 nanostubes were prepared via solid state reaction method, and their tribological properties were studied over a wide range of normal loads and sliding velocities. The size distributions and shapes of sulfides were characterized using transmission electron microscopy and scanning electron microscopy. The results indicated that the NbS2 and TaS2 compounds had tubular structures with the mean diameter of 100 nm and length of 10 mm. The effect of NbS2 and TaS2 nanotubes added in commercial lubricating oil T40, was initially studied using the instrument MS-T3000. The results showed that the antiwear ability of NbS2 and TaS2 as additives was obviously better than that of the normal lubricating oil in ambient conditions. The general frictional properties of the solid lubricant containing TaS2 is better than those of the solid lubricant containing NbS2. The frictional mechanism was discussed."

摘要:
" 利用固相反应方法合成了具有无机类纳米管状结构的NbS2和TaS2纳米管束, 并利用扫描电子显微镜、透射电子显微镜、X射线衍射仪等研究其表面形貌、微观结构和物相组成,探讨了该管状结构的生长机理;利用摩擦学实验机(MT-2300)初步研究了其摩擦学行为. 结果显示所生成的NbS2和TaS2纳米管束,直径约100 nm,长约10 1m.作为润滑油添加剂,在室温大气下摩擦时含NbS2和TaS2的润滑油抗磨性能明显高于无添加的普通润滑油,且含有TaS2的润滑油综合摩擦性能优于含NbS2的润滑油.管状NbS2和T
