中文摘要:
      目的 通过研究电沉积方式对Ni-SiC纳米复合镀层性能的影响,进而改善Ni-SiC纳米复合镀层的性能。方法 采用直流电沉积和脉冲电沉积分别制备Ni和Ni-SiC纳米复合镀层,使用扫描电镜和能谱仪研究镀层的表面形貌和成分,通过测量施镀前后镀件质量差计算沉积速率,采用硬度计测量了镀层的硬度,利用极化曲线和电化学阻抗方法研究镀层在3.5%NaCl水溶液中的耐腐蚀性能,分析了直流电沉积方式和脉冲电沉积方式对镀层各项性能的影响。结果 脉冲电沉积方式制备的Ni-SiC纳米复合镀层的表面形貌更加致密、均匀、光滑,镀层硬度为616.3HV,自腐蚀电流为9.56×10-6 A,比直流电沉积制备的Ni-SiC纳米复合镀层的硬度和耐蚀性能均有所提高。结论 电沉积方式对复合镀层的性能有很大影响,脉冲电沉积方式制备的Ni-SiC纳米复合镀层具有更好的性能。
英文摘要:
      The work aims to improve properties of Ni-SiC nanocomposite coatings by investigating effects of electrodeposition methods on properties of the coating. Ni and Ni-SiC nanocomposite coatings were prepared by DC electrodeposition and pulse electrodeposition, respectively. Morphology and composition of the coatings were studied with scanning electron microscopy and energy dispersive spectrometer, deposition rate was calculated by measuring mass difference between the plating pieces before and after plating, hardness was measured with hardness tester, corrosion resistance of the Ni-SiC nanocomposite coatings was studied in polarization curve and electrochemical impedance methods, respectively in 3.5% NaCl solution, and the effects of DC electrodeposition and pulse electrodeposition methods on properties of the coatings were analyzed. For the Ni-SiC nanocomposite coating prepared in pulse electrodeposition method, morphology was more smooth, uniform and compact, the hardness was up to 616.3HV, self-corrosion current 9.56×10−6 A, both hardness and corrosion resistance were superior to that of the Ni-SiC nanocomposite coating prepared by DC electrodeposition. The properties of composite coatings are influenced by electrodeposition methods to a great extent, the properties of Ni-SiC nanocomposite coatings prepared in pulsed electrodeposition method are much better.
