研究了碳纳米角（CNHs）作为添加剂对自配对碳化硅（SiC）在水中摩擦学性能的影响。摩擦系数随CNH浓度的增加而减小，在接触条件较恶劣时，CNH质量分数为1.00%时摩擦系数最小，为0.04。结果发现，CNH在摩擦表面上形成光滑的碳膜。通过对基体进行激光表面毛化处理，可以主动控制碳膜的形成，使摩擦系数的标准偏差比未毛化处理时降低50%以上。
Effect of carbon nanohorns (CNHs) as additives on tribological properties of self-mated silicon carbide (SiC) in water was investigated. Friction coefficient could decrease with increasing concentration of CNH in water, and minimum friction coefficient of 0.04 was obtained with water containing 1.00 mass% of CNH in severe contact condition. It was found that CNHs form lubricious carbon films on the rubbed surfaces. Formation of carbon film was controlled actively by introduction of laser-surface texturing to substrate, resulting that standard deviation of friction coefficient decreases more than 50% as compared to that without texturing.
