In order to reduce and avoid the impact sliding wear of contact surface between the holding cage and ring in rolling bearings,solid film lubrication such as MoS2 is usually applied to modify the lubrication characteristic of cage surface and ring guide surface of the bearing.The friction and wear characteristics of MoS2 solid lubrication film prepared on 9Cr18 bearing steel surface were studied on a selfdeveloped actuatormotor type test rig for impactsliding friction under dry friction and oil lubrication conditions and different impact frequency,impact force and sliding speed.The results show that the failure mode of MoS2 solid lubrication film is mainly influenced by lubrication state and impact force.The frictional torque of MoS2 solid lubrication film is increased with the enlargement of impact frequency and impact force,and the friction torque in oil lubrication is obviously decreased compared with that in dry friction.The failure mode of impacting sample made by bonded technology is mainly fatigue crack and flaking,while the rotating sample made by spraying shows stable wearing process.
