This paper reports the synthesis of cerium trifluoride CeF nanoparticles in the microemulsion of polybutanediimide 3 Ε½ . T154 rcyclohexanerwater and their tribological properties as additives in lubricating oils. The results show that CeF nanoparticles are 3 Ε½
. spherical and cylindrical in shape size: 25 nm and possess excellent extreme pressure and friction-reducing properties. The maximum Ε½ . nonseisure load PB is increased by 85.3%, and the decreasing percentage of friction coefficient is above 25% as compared with Ε½ Ε½ . Ε½ . . background oil 500SN base oil q 4.6% T154 q 3% calcium alkylsulfonate T101 q 3% methyl-tricaprylamine chloride aliquat336 . These may be caused by the formation of a transfer film in the contact surfaces. However, CeF nanoparticles cannot improve the 3 anti-wear performance of lubricating oil effectively, and the reason may be that F y ion generated by decomposing CeF corrodes the 3 rubbing surfaces.

Lubricity and fatty oiliness additives, also known as friction modifi ers in the tribological vocabulary, are steadily gaining acceptance from lubrication engineers and lubricant formulators. The present communication describes how such additives function in various tribosystems and which parameters
Graphite nanosheets with average diameter of 500 nm and thickness about 15 nm were prepared by stirring ball milling. The tribological behavior of the graphite nanosheets as additive in paraffin oil were investigated with a four-ball and a pin-on-disk friction and wear tester. The wear surfaces of t
