氧离子注入增强尼龙1010的耐磨性

用能量 4 5 0keV ,剂量 1× 10 15/cm2 和 5× 10 15/cm2 及能量 10 0keV ,剂量 3×10 16 /cm2 的氧离子分别对尼龙 10 10进行O+注入改性。以HastC合金球为上球样 ,分别与注入及未注入尼龙 10 10下盘样组成摩擦副 ,在销盘摩擦试验机上评价它们在干摩擦及水润滑条件下的摩擦磨损行为。用扫描电镜 (SEM )观察注入及未注入样品磨损前后表面形貌。研究结果发现 :几种工艺的O+注入均增强了尼龙 10 10的耐磨性 ,提高注入能量比增加注入剂量对增强尼龙 10 10的耐磨性更有效。随着注入样品磨损量的减少 ,与其配摩合金球的磨损量增大。未注入样品的磨损主要表现为粘着、犁沟及塑性变形 ,注入样品的磨损主要为疲劳及三体磨粒磨损。

Improve Wear Resistance of PA1010 by O+ Ion Implanted

The PA1010 was implanted with O + at different energies and doses. The friction and wear behaviors of the ion implanted PA1010 disk rubbing with HastC balls were studied using a pin on disk tribometer under dry friction and distilled lubrication condition. SEM examined the surfaces of un implanted and implanted PA1010 befor and after wear. The results show that the wear resistance of PA1010 is increased with several kinds of implantation technologies and raising implanted energy is more efficient than increasing implanted doses for increasing wear resistance of PA1010. The wear of the HastC is increased with decreasing wear of implanted PA1010. The adhesive, plow and plastic deformation is wearing mechanism for un implanted PA1010 and fatigue, abrasive wear for implanted PA1010.
