摘要
采用水热法,以自制的GO为原料,制备了ZnS-GO纳米杂化材料,然后,将其作为填料填充到环氧树脂(EP)中,探究了其对EP摩擦学性能及磨损机制的影响。采用X射线衍射(XRD)、扫描电子显微镜(SEM)和能谱(EDS)分析了产物的化学组成和形貌特征,并且,利用多功能摩擦磨损试验机对EP复合涂层的摩擦磨损性能进行了分析。结果表明,ZnS纳米粒子均匀分布在GO的层间和表面,增大了GO的层间距,有效地改善了GO的层间堆叠,而GO较大的比表面积为ZnS的生长提供了成核位点,改善了ZnS纳米粒子分散性较差的问题。ZnS、GO和ZnS-GO 3种填料均能改善EP的摩擦学性能,其中,ZnS-GO杂化材料的改善效果最佳;当ZnS-GO的含量为0.8%时,ZnS-GO/EP复合材料的摩擦因数和磨损率分别为0.324和62.4×10^(-6)mm^(3)/(N·m),与纯EP相比,分别降低了47.23%和52.26%。
ZnS-GO nano-hybrid material was prepared by hydrothermal method with self-made GO as raw material,and then filled into epoxy resin(EP)as filler.The influence of ZnS-GO on the tribological properties and wear mechanism of EP was investigated.The chemical composition and morphology of EP composite coating were analyzed by X-ray diffraction(XRD),scanning electron microscopy(SEM)and energy dispersive spectroscopy(EDS).The friction and wear properties of EP composite coating were investigated by multi-function friction and wear testing machine.The results showed that the ZnS nanoparticles were evenly distributed in the interlayer and surface of GO,which increased the layer spacing of GO and effectively improved the interlayer stacking of GO.Moreover,the large specific surface area of GO also provided nucleation sites for the growth of ZnS,which improved the poor dispersion of ZnS nanoparticles.Three fillers,ZnS,GO and ZNS-GO,could improve the tribological properties of EP,and ZNS-GO hybrid material had the best effect.When the addition of ZnS-GO was 0.8%,the friction coefficient and wear rate of ZnS-GO/EP composite was 0.324 and 62.4×10^(-6)mm^(3)/(N·m),respectively,which were reduced by 47.23%and 52.26%compared with pure EP.
