Abstract The tribological behaviour of innovative TiO2 nano-additive water-based lubricant on ferritic stainless steel (FSS) 445 was characterised on a ball-on-disk tribometer. Non-oxidised (clean) and pre-oxidised FSS 445 disks with original rough surfaces were both applied in the tribological tests at room temperature. The results show that the water-based nanolubricants with concentrations of 0.4-8.0 wt% TiO2 can significantly reduce the coefficient of friction (COF) on the two types of disks. The 4.0 wt% TiO2 lubricant exhibits optimal tribological properties, including the lowest COF and the strongest anti-wear ability on the applied balls under all lubrication conditions. The lubrication mechanisms are primarily ascribed to the formation of tribofilm and the ball-bearing effect of the TiO2 nanoparticles, respectively, on the two different disks.
