| 摘 要： | 石墨和炭纤维复合增强尼龙1010在摩擦过程中发生了协同效应，其摩擦系数低于0．12，低载荷下的耐磨性能比纯尼龙提高2个数量级以上；在400N载荷的水润滑下复合增强尼龙材料的耐磨性能明显优于单一炭纤维增强尼龙材料，比其干摩擦下耐磨性能也提高了1～2个数量级。对应水润滑下复合增强材料的磨损表面主要发生了轻微的磨粒磨损，炭纤维被磨平磨细；而干摩擦下则发生了剧烈的热疲劳剥落磨损。

| Abstract: | The synergistic action exists in hybrid fillers of graphite (Gr.) and carbon fiber (CF) reinforced nylon 1010 composites while rubbing against the steel ring. The friction coefficient of Gr.-CF-nylon is lower than 0.12 and the wear resistance is increased more than 2 orders of magnitude than that of nylon in water condition at a load of 200 N. The wear resistance of Gr.-CF-nylon is distinctly higher than CF reinforced nylon only in water condition; meanwhile, it is increased by 1~2 orders of magnitude than that in air condition at a load of 400 N. The worn surfaces were analyzed by scanning electron microscope (SEM). It is found that the main mechanism of composites is slight abrasive wear and carbon fibers are worn down and smoothly. By comparison, thermo-fatigue wear with severe spalling arouse in the rubbing surface of composites in air condition. |
