The Influence Of Metal Oxides And Polystyrene Nanopaticles To Oil In Friction And Anticorrosion

Nanometer materials, due to their unique properties in thermodynamics, opticsand semiconductor's optical catalyze, have been gradually used in oil, to develop thefrictional property of base oil. In order to develop the integrate property of oil, somedifferent nanometer materials were prepared, and dispersed in oil. The influences ofthese nanometer materials have been researched, especially in the friction and theanticorrosion.In this paper, some nanometer oxides were prepared, using direct deposition andpotentiometer. The average diameters of these particles were detected by zetapotentiometer. The result shows that the average diameter of the inorganic nanometermaterials, which were prepared using directly deposition, are much larger than2000nm, and only the diameter of TiO₂ by potentiometer is about 100nm.All this nanometer oxides can increase the anticorrosion property of oil, especially thenanometer TiO₂. The concentration of the addictive TiO₂ and the acidity of the systemcan influence oil's property. When the concentration is 2.4%, the system is middlingacidity, the time of was prolonged from 1 hour to about 400 hours, in addition, thewear scar diameter was decreased from 2.1mm to 1.3mm, under 800N load. Moreover, a series of polystyrenes which contain functional group or not, weresynthesized. The results show that the length of the carbolic chains can influence theaverage diameter of nanopaticles in oil. All the organic nanoparticles can improve theoil's property in friction, but decrease the oil's property in anticorrosion.
