【摘要】 采用化学复合镀的方法,在45#钢衬底上制备纳米碳管(CNTs)-(Ni-P)复合材料。探讨了该复合材料的制备技术及工艺条件,通过对实验结果的观察和分析,确定了制备CNTs-(Ni-P)复合材料的最佳工艺条件。利用透射电镜(TEM)观察纳米碳管的结构;用扫描电镜(SEM)观察纳米碳管形貌及其在复合材料中的分布;利用原子力显微镜(AFM)观察复合材料表面的粗糙度。同时还对纳米碳管复合材料的耐磨性进行了初步的测试。实验结果表明,该复合材料的耐磨性明显好于未镀及单纯镀镍材料。更多还原

【Abstract】 The CNTs-(Ni-P) composites were prepared by electroless plating on 45~# steel substrate, and the optimum composition and operating conditions were obtained. The TEM was used to observe the CNTs’ structure,the SEM was used to observe the appearance and distribution of the CNTs in the composites and the AFM(atomic force microscopy) was used to analyze the roughness status of the composite surface. The influence of the CNTs on the tribological performance of the composites is discussed. The results show that the CNTs-(Ni-P) composites have better wear-resistance than the uncoated substrate and the substrate coated with nikel.更多还原
