Abstract
- MoSe 2 nanoparticles were successfully synthesized by hydrothermal method and treated with a novel dispersion method, ultrasonic dispersion in water. The tribological behaviors and wear mechanisms of MoSe 2 nanoparticles as oil additives were investigated using a reciprocating ball-on-disk tribo-meter. The results showed that the average friction coefficient and wear rate decreased by 43% and 87% respectively with the addition of the treated MoSe 2 nanoparticles compared with white oil. The lubrication mechanism was investigated and can be interpreted as that the MoSe 2 had smaller particle size after being ultrasonically dispersed in water, which were beneficial to the formation of the tribo-film. 1. This study proposed a method to treat MoSe 2 nanoparticles that were synthesized by hydrothermal method. 2. The lubrication effects of white oil were greatly enhanced with the addition of MoSe 2 nanoparticles. 3. The tribological mechanism was discussed. [ABSTRACT FROM AUTHOR]
