Tribochemistry of gadolinium dialkyldithiophosphate

摘要: Abstract In the present paper, tribological behaviors of gadolinium dialkyldithiophoshate (GdDDP) were evaluated on friction testers. There-after, tribochemistry GdDDP investigated through scanning electron microscopy (SEM), Auger spectroscopy (AES) and X-ray photoelectron (XPS). The results indicated that possesses very good antiwear friction-reducting capacities; boundary film diffusion layer with metallic gadolinium, phosphate organo-sulfide played dominant roles in reducing wear.
