This work demonstrats a convenient and effective approach to synthesize WSe 2 nanorods at only 600 °C in argon atmosphere after ball milling. The friction and wear properties of WSe 2 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 WSe 2 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 WSe 2 nanorods as lubrication additive was discussed.
