摘要

This work describes the feasibility of forming titanium oxide nano-oils using a modified plasma arc system. The high temperature that is generated by the plasma arc system is used to heat up and vaporize the bulk metal. Titanium oxide gas and particles are then induced into the collection piping by an induction system. They are then thoroughly mixed, with pre-condensed paraffin oil is mixed, and rapidly cooled in a process that contributes to grain nucleation and prevents particle size growth. Hence, nano-oils, with small spheres of titanium oxide can be obtained and finally stored in a collection tank. A friction test is performed using an ATE-77 Reciprocal Tribological Tester made by Cameron-Plint Tribology Limited, England. The viscosities of the nano-oils were measured using a DVIII + LVDV — 1IIUCP rheometer in a rate-sweep mode over a shear-rate range of 200-1900. Results indicate that the nano-oils mixed with spherical titanium oxide can be made using a modified plasma arc system. The viscosity of nano-oil consistently exceeds that of the paraffin oil enlarging the partial elastohydrodynamic lubrication (EHL) area with a complete lubricating film between two move iron surfaces. The complete lubricating film provides good performance, then warranting the use of the titanium oxide nano-oils as revolutionary lubrication agent.
