Abstract

Neodymium dialkylthiophosphate (NdDDP) with alkyls of isopropyl and isooctyl were synthesized by exchanged reaction respectively. The structures of the two NdDDPs were determined using IR and XRD. The properties of anti-wear and friction-reducing of the two additives were investigated with four ball experiment and the commercial anti-wear additive ZDDP was selected as control. The elemental analysis of the wear scars after 10 s friction at low stress was investigated by EDXA (Energy Dispersion Analysis of X-ray). The primary results showed that the NdDDPs possessed better lubrication ability than ZDDP. This might mainly be contributed to the formation of a boundary film containing Nd₂O₃, FeS and sulphate, phosphate, organo-sulfide, etc., and a neodymium-rich diffused layer which changed the crystal structure of the surface of friction materials.
