Abstract

Aqueous rolling liquids with different concentrations of TiO₂ nano-particles are prepared. The dispersing mechanism of nano-TiO₂ in the rolling liquid is studied by FTIR and TEM. Wettability and viscosity of these rolling liquids is evaluated based on Dataphysics OCA50 contact angle measuring device and SYD-265C viscometer, respectively. New viscosity empirical formula that suitable for nano-TiO₂ aqueous rolling liquid is proposed. The tribological property is also investigated by the MM-WIA universal tribological tester. The results indicate that with the increase in the nano-particle's addition, the contact angle gradually decreases, whereas the viscosity rises, which would contribute to ameliorating the frictional behaviour of aqueous suspensions. The aqueous suspension with 0.7 wt% TiO₂ possesses excellent friction reduction and anti-wear properties.
