| Abstract: | The morphology and size of the CaCO 3 nanoparticles were examined by transmission electron microscope (TEM). The lubricating oils with CaCO 3 nanoparticles were prepared. The tribology tests were carried out in four-ball tribotester. The surface morphology and chemical element states have been tested and analyzed by scanning electron microscope(SEM) and X-ray photoelectron spectrum(XPS). The research results show that the lubricating oil with 0.6% CaCO 3nanoparticles has optimum properties of friction-reduction and wear resistance.The mechanism of friction-reduction and wear resistance was discussed. |
