    摘要:

    采用X射線衍射(XRD)、掃描電鏡(SEM)、能譜分析(EDS)等方法研究了脈沖電沉積法制備納米晶Ni和納米晶Ni-Co合金鍍層的組織結構、表面形貌和成分。用浸泡法和電化學極化法研究了納米晶Ni和不同Co含量的納米晶Ni-Co合金鍍層在3.5% NaCl (質量分數(shù)，下同)和5% HCl溶液中的腐蝕行為。結果表明： 通過脈沖電沉積法制備的Ni和Ni-Co合金鍍層具有典型的納米晶結構；隨著含Co量的增加，鍍層的晶粒尺寸減小，硬度增加；所制備的納米晶Ni-Co合金鍍層組織結構均勻致密，其在3.5% NaCl溶

    Abstract:

    The microstructures, the surface morphology and the composition of nanocrystalline Ni and nanocrystalline Ni-Co alloy prepared by pulse electrodeposition have been studied by XRD, SEM and EDS. The corrosion behaviors of nanocrystalline nickel and Ni-Co alloys in the solutions containing 305% (mass fraction) NaCl and 5% (mass fraction) were investigated by soak method and electrochemical polarization method respectively. The experimental results indicate that typical nanocrystalline nickel and Ni-Co alloy coatings can be synthesized by pulse electrodeposition, and the alloying element Co had an effect of solution strengthening and grain size refinement. The nanocrystalline Ni-Co alloy is dense in nature and it exhibited better corrosion resistance in 3.5% (mass fraction) NaCl solution and 5% (mass fraction) HCl solution than the nanocrystalline nickel. The surface morphology of all samples after corrosion in 3.5% (mass fraction) NaCl solution show good corrosion resistance, however, the samples were uniformly corroded in 5% (mass fraction) HCl solution.
