Dialkyldithiophosphate (DDP) capped Fe nanoparticles were synthesized in a two-phase system of tetrahydrofuran/saturated electrolyte with NaH2PO2 as reductant and DDP as modification agent.The structure and mophologies of surface modified Fe nanoparticles were characterized by FTIR
TGA and TEM. The tribological properties were investigated by four-ball test machine
and the worn surfaces of the balls were analyzed by scanning electron microscopy and EDS.The results showed that the surface modified Fe nanoparticles exhibited excellent solubility in low polar organic solvents and good anti-wear properties.SEM result of wear scar indicated that the main reason for the tribological properties was the formation of a layer of film composed of Fe
