摘要
以MoS2、玻璃纤维(GF)、纳米Al2O3等为填料制备了聚四氟乙烯(PTFE)复合材料,研究微米、纳米MoS2对复合材料摩擦学性能、磨损表面形貌的影响。结果表明:纳米MoS2填充的PTFE复合材料的硬度较大、密度较小,且磨耗量、摩擦因数均小于微米MoS2填充的PTFE复合材料;在MoS2/PTFE复合材料中填充玻璃纤维和Al2O3,可大幅降低材料的磨耗量,其中玻璃纤维填充的纳米MoS2/PTFE复合材料耐磨损性能最好,且硬度和密度最高,并具有相对较低的摩擦因数。
The Polytetrafluoroethylene(PTFE) composites were prepared with MoS2, glass fiber(GF) and nano-Al2O3 as fillers. The effect of micro and nanometer MoS2 on the tribological properties and worn surface morphology of composite materials was studied. The results show that PTFE composite material filled with nano-MoS2 has a higher hardness and lower density, lower wear loss and friction coefficient than that of filled with micron MoS2. The wear loss can be reduced greatly by filling GF and nano-Al2O3 in the MoS2/PTFE composite material, among which the MoS2/PTFE composite material filled with GF has the best performance of wear resistance, the highest hardness and density, and relatively lower friction coefficient.
