| 摘 要： | 探讨了纳米SiO2（n-SiO2）对火焰喷涂尼龙（Nylon）1010涂层干摩擦磨损性能的影响，采用MRH-3型环-块摩擦磨损试验机对不同n-SiO2含量的尼龙1010涂层的干摩擦磨损性能进行了测试；并利用扫描电子显微镜（SEM）对复合涂层的磨损表面进行观察。结果表明：n-SiO2的加入能明显提高尼龙涂层的耐磨性，降低摩擦因数，疲劳磨损、粘附磨损及犁切现象明显减轻，当n-SiO2含量为1．5％时复合涂层综合性能较好。 |

| Abstract: | The effects of nano-SiO2 on the dry sliding wear of flame spray Nylon1010 composite coatings were investigated. The friction and wear behaviors of the Nylon1010/n-SiO2 composite coatings were examined using a MRH-3 friction and wear tester. Based on the morphological observation of the worn surfaces, the possible wear mechanism was discussed. The result showed that nano-SiO2 particles can increase the wear resistance of Nylon1010 matrix, the wear mechanism of composite coating is mainly abrasive and mild adhesion wear as they slid against the steel counterpart in dry ambient condition. The Nylon1010 composite coatings containing 1.5 % SiO2 nanoparticles showed the best friction-reducing and antiwear behavior. |
| Keywords: | nano-SiO2 flame spraying Nylon1010 coating friction and wear |
