The tribological performance and rolling lubrication properties of the BP/TiO_2 nanocomposites as water-based lubrication additives (BP/TiO_2-WL) were investigated by the ball-on-disc tribometer and four-high rolling mill. The results indicated that the average coefficient of frictions (COFs) and wear rate of the 0.08 wt% BP/TiO_2-WL were reduced by 24.5% and 59.5%, respectively, compared with ultrapure water. The lubrication mechanisms of the BP/TiO_2-WL were dominated by the synergistic effect between the BP nanosheets and TiO_2 nanoparticles and the formation of tribological reaction films. In addition, due to the addition of the BP/TiO_2 composite nanofluids, the rolling force and surface roughness of the titanium alloy plate during the rolling process were decreased by 17.5% and 32.2%, respectively. Therefore, BP/TiO_2 nanocomposites as water-based lubrication additive have shown potential application in the field of titanium alloy plate cold rolling.
