| Abstract: | A zirconia nanoparticle coated with a layer of stearate is characterized by FTIR, ESR, DSC, TGA and XPS. The results show that the surface modification layer effectively prevents the adsorption of water on the surface of the ZrO2 nanometer size core. The binding of Zr4+ and stearate is through bidentate chelating coordination. The lubrication properties of the modified ZrO2 nanoparticles as an additive in liquid paraffin are also primarily investigated. The results show that such ZrO2 nanoparticles have good friction reduction and antiwear properties. |
