摘 要
通过电沉积方法制备了Ni-W/SiC纳米复合镀层,利用扫描电子显微镜(SEM)、能谱分析(EDS)和X射线衍射分析(XRD)研究了SiC含量对该复合镀层结构和性能的影响,采用电化学方法研究了Ni-W/SiC纳米复合镀层在质量分数为3.5% NaCl溶液中的耐蚀性。结果表明:SiC纳米颗粒能促进镀层晶粒的形核及生长,显著改变镀层的晶体结构,提高镀层的硬度、耐磨性及耐蚀性;SiC含量过低对镀层耐磨性提高有限,含量过高又容易导致SiC纳米颗粒团聚,影响其分散性,因此当SiC的质量浓度为6~9 g/L时所制备的Ni-W/SiC纳米复合镀层具有最佳的性能。

Abstract
Ni-W/SiC nano-composite coatings were prepared by electrodeposition method. The effects of SiC content on the microstructure and properties of Ni-W/SiC composite coatings were investigated by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and X-ray diffraction (XRD). The corrosion resistance of the composite coating in 3.5 wt.% NaCl solution was studied by electrochemical method. The results show that the addition of SiC nanoparticles could promote the nucleation and growth of crystals in the coatings, and could change the crystal structure, which would improve the microhardness, wear resistance and corrosion resistance. Ni-W/SiC nano-composite coating prepared in SiC concentration of 6 to 9 g/L had the best properties. Because higher concentration of SiC would lead to agglomeration of nanoparticles and thus impair their dispersibility. And the improvement of wear resistance was not ideal, if concentration of SiC was too low.
