| 摘 要： | 分别用前驱体分解法与剥层重堆法制备出二硫化钼纳米球(nano-MoS2)与聚甲醛/二硫化钼夹层化合物(MoS2-IC),再利用制备的nano-MoS2、MoS2-IC与微米二硫化钼(micro-MoS2)作为原料制备出POM/MoS2复合材料.在真空摩擦磨损试验机上考察了复合材料的摩擦学性能,结果表明,POM/nano-MoS2复合材料具有最好的摩擦学性能,POM/MoS2-IC复合材料次之,而POM/micro-MoS2复合材料性能与POM比没有改善;SEM分析显示,POM及其复合材料主要发生的是疲劳磨损,POM/nano-MoS2的疲劳磨损最轻,POM/MoS2-IC疲劳磨损最严重,POM与POM/micro-MoS2除了疲劳磨损外,还存在明显的粘着磨损. |

| Abstract: | Molybdenum disulfide nano-balls(nano-MoS 2) and POM/MoS 2 intercalation compound(MoS 2-IC) were prepared respectively by the precursor method and the exfoliating-restacking method.The two obtained MoS 2 powders and commercial bulk MoS 2(micro-MoS 2) were respectively added into POM so as to get POM/MoS 2 composites.Tribological properties of the obtained composites were investigated on a vacuum tribometer.Results show that the POM/nano-MoS 2 composite had the best tribological properties.POM/MoS 2-IC also p... |
