摘要
为了揭示纳米粒子的协同作用机理,以少层石墨烯为载体,纳米铜作为负载金属粒子,在可生物降解润滑油基础上,分别采用分子水平混合和机械混合方法制备了石墨烯/铜混合纳米流体。在确定的石墨烯/铜比例及纳米粒子的质量分数条件下,进行了微量润滑切削AISI 304不锈钢的单因素试验研究。结果表明,配方合适的分子水平混合纳米流体协同润滑作用优于机械混合纳米流体,MQL加工时可降低切削温度,提高表面质量,减小刀具磨损。
In order to reveal the synergistic mechanism of nanoparticles,graphene/copper hybrid nanofluids are prepared by molecular-level mixing and mechanical mixing methods with biodegradable lubricant as base oil,by using few-layer graphene as the carrier and nano-copper as the supported metal particles,respectively.Under the conditions of the certain graphene/copper ratio and the mass fraction of nanoparticles,a single-factor experimental study of the minimal quantity lubrication cutting AISI 304 stainless steel is conducted.The results show that the synergistic lubrication effect of the molecular-level mixed nanofluid with the appropriate formulation is better than that of the mechanically mixed nanofluid,and the cutting temperature and cutting tool wear could be reduced,the surface quality could be improved during MQL processing.
