| 摘 要： | 采用UMT-3MT往复式滑动摩擦磨损试验机,研究在透明质酸钠(SHA)润滑介质下,氧化石墨烯(GO)对基体材料超高分子量聚乙烯(UHMWPE)摩擦学性能的影响.利用高分辨扫描电子显微镜(HR-SEM)和MicroXAM非接触式3D表面轮廓仪观察试样表面磨痕形貌并计算其磨损率.结果表明:在SHA润滑介质下,无机填料GO的添加显著降低UHMWPE基复合材料的磨损率,但是,GO的添加对复合材料稳态摩擦系数和残留在SHA润滑介质中的磨粒特征无明显影响.无机填料GO的添加增强了UHMWPE在SHA润滑介质下的耐磨性能.

| Abstract: | The tribological property of UHMWPE and its composites reinforced by Graphene Oxide (GO) were investigated using the UMT-3MT reciprocating friction testing apparatus under the lubrication medium of sodium hyaluronate (SHA). The surface topographies and the wear rate of these composites were observed and evaluated by a high-resolution scanning electron microscope and an Micro-XAM three-dimensional surface profiler. The results demonstrate that the wear rate of GO/UHMWPE composites was reduced significantly as the increasing content of GO under the lubrication medium of SHA, but no significant differences were found in the steady coefficient of friction and the characteristic of the wear debris in SHA was the same as that produced by the pure UHMWPE. The wear resistance of UHMWPE was improved markedly with the addition of GO filler. |
