Tribological behavior of nanodiamond-dispersed lubricants on carbon steels and aluminum alloy

▶ Nanodiamond particles have a better dispersive capability and a higher viscosity in the base oil than commercial oil. ▶ There are optimal concentrations using nanodiamond particles as an antiwear additive in the base oil. ▶ Nanodiamond particles as a solid additive in oil lubricants improve the tribological behavior of carbon steel as well as that of aluminum alloy. However, their wear mechanisms are different.
