Abstract

Polytetrafluoroethylene/Poly(methyl methacrylate) (PTFE/PMMA) composite was prepared by mixing PTFE into PMMA matrix which synthesized by the PMMA powder mixture and methyl methacrylate (MMA) liquid mixture. The effects of the filling mass ratio of PTFE and powder/liquid (P/L) ratio on the friction and wear properties of PTFE/PMMA composites against bearing steel were studied by a ball-on-disk tribometer. Fourier transform infrared (FTIR), field emission scanning electron microscopy (FESEM), and energy dispersive X-ray spectroscopy (EDS) were used to characterize the synthesis of PTFE/PMMA composite. The shore hardness and glass transition temperature () were obtained respectively by shore hardness tester and differential scanning calorimetry (DSC). The results show that the friction coefficient and wear rate of PMMA based composite, comparing with the unfilled PMMA, can be significantly reduced by filling with PTFE. With the increasing of PTFE filling mass ratio, the wear rate of PTFE/PMMA composite increases. The friction coefficient and wear rate of the unfilled PMMA and PTFE/PMMA composite generally decrease with the P/L ratio increasing. The main wear mechanism of the unfilled PMMA is adhesive wear. While the main wear mechanisms of PTFE/PMMA composites are fatigue wear and abrasive wear.

摘要

聚四氟乙烯/聚甲基丙烯酸甲酯（PTFE/PMMA）复合材料是通过将聚四氟乙烯混入由聚甲基丙烯酸甲酯粉末混合物和甲基丙烯酸甲酯（MMA）液体混合物合成的聚甲基丙烯酸甲酯基体中制备而成。采用球盘摩擦磨损试验机研究了聚四氟乙烯填充质量比和粉液比（P/L）对PTFE/PMMA复合材料与轴承钢摩擦磨损性能的影响。利用傅里叶变换红外光谱（FTIR）、场发射扫描电子显微镜（FESEM）和能量色散X射线能谱仪（EDS）对PTFE/PMMA复合材料的合成进行了表征。分别通过邵氏硬度计和差示扫描量热法（DSC）获得了邵氏硬度和玻璃化转变温度（）。结果表明，与未填充的聚甲基丙烯酸甲酯相比，填充聚四氟乙烯可显著降低聚甲基丙烯酸甲酯基复合材料的摩擦系数和磨损率。随着聚四氟乙烯填充质量比的增加，PTFE/PMMA复合材料的磨损率增加。未填充的聚甲基丙烯酸甲酯和PTFE/PMMA复合材料的摩擦系数和磨损率通常随P/L比的增加而降低。未填充的聚甲基丙烯酸甲酯的主要磨损机制是粘着磨损。而PTFE/PMMA复合材料的主要磨损机制是疲劳磨损和磨粒磨损。
