Highly effective friction modifiers from nano-sized materials
Synthesis and the tribological properties of oil-soluble friction modifiers made from surface-modified (lyophilized) nanoparticles of molybdenum trisulfide (nano-MoS3) are described. The synergistic effect of nano-MoS3 and zinc dialkyldithiophosphate (ZnDDP) is demonstrated. Addition of the latter is effective at high temperatures and low concentrations.
