| 摘 要： | 本次制备纳米Cu采用的是化学还原反应生成分散的纳米Cu单质。纳米Cu进行表征分析时 ,主要通过X—衍射仪分析和扫描电镜观察分析 ,反复对比观察 ,找到较佳的表征分析方法。润滑试验选用的四冲程发动机油作为基础试验油 ,将制备不同的超微粒子以不同的比例的润滑油 ,磨损实验为进行传统润滑油、纳米润滑油的抗磨减摩性能对比试验研究。试验结果发现 :纳米颗粒不仅具有良好的抗磨减摩性 ,并且一定条件下 ,平均粒径小 10 0nm的纳米Cu颗粒的抗磨减摩效果远优于传统润滑油 ,可能成为新一代润滑油的抗磨减摩添加剂。

| Abstract: | An optimal scheme was found by comparison of two results obtained separately from X-ray diffraction and SEM methods. The 4-storke engine oil is used as test lubricant. Cu nano-particles were used as additive dispersed into ordinary oils with different weight proportion and nano-particles' antiwear and reducing friction performance is compared with traditional oil .The results indicated that Cu nano-particle has antiwear and friction-reducing properties better than the traditional oil .It will be a new lubricant. |
