Worn surface morphology was examined with scanning electron microscopy, and wear volume was measured with a Talysurf 5P-120 topographer. Results show that CNTs, in mass concentration of 0.01%~0.1%, can greatly improve the antiwear ability of lubricating oil. With addition of CNTs, the maximum reduction of wear rate is about 57%, and scratches on the worn surfaces become slighter and more uniform. The maximum decrease of friction coefficient is about 15% with 0.025% CNTs additive at the load of 300 N. The antiwear mechanism has been discussed.

结果表明：碳纳米管作为润滑油添加剂表现出优良的抗磨性能，在质量分数仅为0.0125%～0.1000%时，润滑油的抗磨性能显著提高；在质量分数约为0.0500%时其抗磨效果最佳，磨损率降低幅值达57%；在较高载荷下，添加0.0250%的碳纳米管能够使其摩擦系数减小约15%，但随着碳纳米管质量分数的增加，摩擦系数迅速提高；含碳纳米管润滑油的磨斑表面平整，划痕较细且分布均匀。
