| Abstract: | The tribological characteristics of ZnO nano particles as lubricating oil additive were studied by experiments in this paper. The model of acting mechanism was proposed. The performances of antiwear and friction reduction in lubricating oil are markedly improved by adding ZnO nano particles and dispersants together. The acting mechanism is that dispersants absorb on the surface of ZnO nano particles cluster, and then they absorb on the surface of friction pair together. ZnO nano particles cluster becomes smaller unit cell under the action of shearing force. ZnO nano particles are in the state of melt or semi melt when the load increases, which results in debasing wear and reducing friction. |
