This work demonstrats a convenient and effective approach to synthesize WSe₂ nanorods at only 600 °C in argon atmosphere after ball milling. The friction and wear properties of WSe₂ nanorods as additives in two kinds of base oil, GyT130 oil and 60N oil were systematically investigated. Compared to base oil, the friction coefficient of the base oil containing WSe₂ nanorods was obviously reduced and the wear behaviour was improved. The nanorods in the 60N base oil showed better tribological properties than that in the GYT130 oil. The friction-and-wear mechanism of the WSe₂ nanorods as lubrication additive was discussed.
