摘　　要：在多孔阳极氧化铝(AAO)模板上的有序纳米孔中电化学沉积过渡金属Co作为催化剂,通过催化化学气相沉积(CCVD)法制备出有序、均匀的非晶态碳纳米棒定向膜.采用扫描电子显微镜(SEM)、能谱仪(EDS)及激光Raman光谱等方法分析了非晶态碳纳米棒定向膜的微观结构和形貌,并讨论了其摩擦因数与载荷及速度的关系.实验结果表明,非晶态碳纳米棒定向膜具有较小的摩擦因数,并且随着载荷的增加而减小,随速度的增加而先减小后增大,当滑动速度为0.18m/s时摩擦因数最小.A transition metal Co as catalyst was electrodeposited in the ordered nanosized pores of anodic aluminum oxide (AAO) template, and the aligned film of amorphous carbon nanorods was obtained by catalytic chemical vapor deposition. The microstructures and morphology of the aligned film were investigated by scanning electron microscope (SEM), energy dispersive X-ray spectroscopy (EDS) and laser Raman spectroscopy. The friction properties were performed at different load and velocity. The aligned film of amorphous carbon nanorods has a low friction coefficient. The friction coefficient first decreased then increased with increase in sliding velocity, and was the minimum at 0.18 m/s.
