摘要：
The effects of ultra-dispersed diamond (UDD) on the friction force, wear, and temperature of tri-bological pairs have been investigated. The experimental tests were carried out on a modified piston ring-cylinder liner bench tester with different particle mass fractions of 0, 0.02%, and 0.10%. The results show that compared with a pure fluid, the mixture of the fluid and UDD not only reduces the friction and wear, but also reduces the bulk temperature of the specimen. The mechanism by which the UDD lubricant improves the tribological properties has some relationship with surface topography, because it can increase the bearing capability of surfaces.
