| Abstract: | Stearic acid capped Fe3O4 nanoparticle was synthesized by using microwave hydrothermal method. The product was discussed on structure by IR. It has good dispersion and stability. A four-ball tribometer was employed to evaluate its tribological properties. The best tribological performance could be obtained with the coefficient of friction of 0.025,wear scar diameter of 0.47 mm,when the addition weight ratio of Stearic acid capped Fe3O4 nanoparticle in liquid paraffin is 1.00%. |
