【英文摘要】There are 23 dialkyldithiocarbmate rare earth complexes were synthesized through designing of molecule structure of rare earth complexes. Tribological properties and lubrication mechanism of these complexes as additive of lubricating grease or water were investigated. These complexes were stably dispersed in lubricating oil by modification using organic compound. Lubrication properties and mechanism of the dispersed complexes in lubricating oil were investigated. Tribological properties of rare earth fluoride in lubricating grease were deeply studied and associated with electron struture, bond and thermodynamics parameter of the rare earth fluoride. Effect of injecting of Ce ion on GCr15 steel, Cerium oxide to Ni based flame spray coating and Fe-Mo-S alloy on antiwear properties were investigated. Study on tribological properties of self-lubricating rare earth fluoride compoistes were conducted.
