Cubical AlF 3 nanoparticles have been successfully synthesised by immersing Ti 3 AlC 2 powders in hydrofluoric acid‐assisted solvothermal reaction. The as‐prepared products are characterised by an X‐ray diffractometer and scanning electron microscopy. The results showed that the AlF 3 nanoparticles have a cubical structure and the sizes of nanoparticles are about 100 nm in side length. The tribological properties of cubical AlF 3 nanoparticles as a lubrication additive in 100SN base oil were investigated by a UMT‐2 ball‐on‐disc friction and wear tester. The wear scars were measured by a common optical microscope. The results show that under determinate conditions, the friction coefficient of the base oil containing AlF 3 nanoparticles is lower than that of pure base oil, and the base oil containing 1 wt% AlF 3 samples presented good tribological performance under the load of 15 N. The formation of tribofilm on the rubbing surface could explain the good friction of AlF 3 nanoparticles as additives.
