| 摘 要： | 通过原位聚合制备了纳米Al2O3增强单体浇铸聚酰胺复合材料(简称PA6／Al2O3)。在磨损试验机上考察了纳米粒子含量和试验条件对其摩擦性能的影响，并利用扫描电子显微镜对其摩擦性能和磨损机制进行了考察。分析结果表明：纳米Al2O3填料可提高单体浇铸PA6的耐磨性，其含量在3％左右时增强效果最好；随着载荷的增加，PA6／Al2O3的磨损率平缓增大，而摩擦系数逐渐减小，其摩擦系数值较单体浇铸PA6的摩擦系数稍大。

| Abstract: | Nano-Al 2O 3-reinfored polyamide composites (PA6 /Al 2 O 3) were prepared via in-situ polymerization. The effects of the content of n ano-particles and wear condition on the tribological properties of the composit es were measured using an MM-200 block on ring wear tester. The wearing surface was viewed with scanning electronic microscope and metallurgical microscope and the wearing mechanism was proposed. It was found that nano-Al 2O 3 improved the wear resistance of monomer casting polyamide with the optimal content of nan o-Al 2O 3 being 3 wt%. With the increase of load, the wear rate of PA6/Al 2O 3 i ncreased slowly while its friction coefficient decreased gradually. However, the friction coefficient of the composite was a little larger than that of neat mon omer casting polyamide. |
