New Technique for Developing of Nano-magnetic lubricating oil Using Non-equilibruim Plasma at Normal Pressure

采用等离子体手段,在自行研制的等离子体反应装置上,对常压下气-液两相混合介质进行活化和电离制备纳米磁性润滑油,通过控制脉冲等离子体的放电参数,优化五羰基铁的热解温度,使纳米磁性润滑油反应流程缩短至2个小时左右;制备的纳米磁性润滑油流动性好,纳米磁性颗粒均在10nm左右,饱和磁化强度接近800G(未浓缩)。实验研究表明,等离子体手段能够实现向反应系统提供气-液分子断键复合重新组合所需要的活化能,是加快合成纳米磁性润滑油的一种有效的新方法。

The magnetic lubricating oil of nitride was developed in a gas - liquid reactor by the plasma activated and ionized reactants at atmospheric pressure. The reaction time was shortened to 2 hours by controlling discharge parameter of plasma and optimizing the thermal decomposition temperature of Fe （CO）5. The magnetic lubricating oil is composed of nanoparticles with about 10 nm gain size, and has good fluidity with saturate magnetization of 800G（ non -concentrated）. The experiment researches show that plasma can supply the needed activation energy for the band broking of the gas - liquid reactant molecules which are recombined and forming magnetic lubricating oil, and that plasma activation at normal pressure is an effective method for synthesis of magnetic fluid.
