| 摘 要： | 通过钢/类金刚石(DLC)薄膜摩擦副在干摩擦4、122油和L252脂润滑条件下的球-盘摩擦学试验,对比分析润滑条件、载荷、速度对DLC膜摩擦系数的影响,利用原子力显微镜分析膜层磨损性能,研究润滑条件对膜层磨损寿命的影响。结果表明:油、脂润滑下DLC膜最大静摩擦系数分别减小了17%和38%;从0～2000 r/min转速范围内,DLC膜摩擦系数随转速增加而减小,油润滑下相比干摩擦DLC膜摩擦系数小15%～48%,脂润滑下相比干摩擦DLC膜摩擦系数在0～500 r/min转速范围小,超过500 r/min后干摩擦DLC膜摩擦系数小;油和脂润滑条件下,DLC膜层的磨损程度明显降低,磨损率相比干摩擦条件下分别减小了7.4倍和15.5倍。 |

| Abstract: | The diamond-like carbon(DLC) films were coated on steel substrates.The surface microstructures,before and after the test,were characterized with atomic force microscopy.The results show that the DLC films significantly decrease the friction,and that the lubricant type and rotation rate strongly affect the friction coefficient.For example,the 4122 oil and L252 grease decrease the maximum coefficient of static friction(COF) by 17% and 38%,respectively,as compared with that of the control sample(air at the int... |
