纳米MoS2含量对纳米微量润滑磨削CFRPs的影响

为了研究磨削碳纤维复合材料(CFRPs)时，纳米二硫化钼(MoS₂)含量对纳米微量润滑效果的影响，制备了不同质量分数(0%，3%，6%，9%，12%)的纳米MoS₂和棕榈油混合液，作为纳米微量润滑油液，对碳纤维复合材料进行磨削加工.使用光学显微镜，观测分析碳纤维复合材料的表面粗糙度、表面形貌.使用测力仪对磨削力进行测量，并通过磨削力计算出磨削力比.最后对纳米(MoS₂)在纳米微量润滑磨削过程中的作用机理进行了阐述.结果表明，当纳米(MoS₂)质量分数为9%时磨削力比最低，为0.0632，表面粗糙度R_○a值最小，为1.86μm，且表面碳纤维损伤最小.

Effect of Nano MoS2Concentrations on Nano Minimum Quantity Lubrication in CFRPs Grinding

To investigate the effect of nano MoS₂ concentration on minimum quantity lubrication(MQL)in grinding carbon fiber reinforced plastics(CFRPs)， the grinding experiments of CFRPs were carried out with lubricating oils of various concentrations(0%， 3%， 6%， 9%， and 12%)of nano MoS₂ in palm oil. The surface roughness and morphology of the CFRPs were studied by optical microscopy. The grinding forces were measured by dynamometer， and the grinding force ratio was calculated and analyzed. Also， the CFRPs grinding mechanism with MQL of various nano MoS₂ concentrations was explained. The results show that when the mass fraction of nano MoS₂ reaches 9%， the grinding force ratio reaches the lowest value of 0.0632， and the quality of surface roughness with R_○aof 1.86μm and surface morphology of CFRPs are both better than those with other concentrations.
