一种Ni-Cr-SiO2纳米复合镀层、电镀液以及电镀方法
摘要：
本发明涉及一种Ni‑Cr‑SiO2纳米复合镀层、电镀液以及电镀方法，该纳米复合镀层，包括如下成分及其质量百分含量：Ni 72.00‑88.00％、Cr 10.00‑20.00％、SiO21.00‑5.00％，余量为不可避免的杂质。本发明还提供该纳米复合镀层的电镀液以及电镀方法。本发明的Ni‑Cr‑SiO2纳米复合镀层晶粒尺寸较小、表面光滑、结构致密；Ni‑Cr‑SiO2纳米复合镀层具有高硬度、耐蚀性好及表面形貌优异的特点，显微硬度可达1329HV，在3.5wt.％NaCl溶液中的交流阻抗可达6997Ω/cm2。
摘要（英）：

The invention relates to a Ni-Cr-SiO2 nanometer composite plating layer, electroplating liquid and an electroplating method. The nanometer composite layer comprises the following components in percentage by mass: 72.00-88.00% of Ni, 10.00-20.00% of Cr, 1.00-5.00% of SiO2, and the balance of inevitable impurities. The invention further provides electroplating liquid and an electroplating method of the nanometer composite plating layer. The Ni-Cr-SiO2 nanometer composite plating layer is smaller in grain size, smooth in surface and compact in structure, and has the characteristics of high hardness, good corrosion resistance and excellent surface topography; the microscope hardness can reach 1329 HV; and the alternating-current impedance in 3.5 wt.% of NaCl solution can reach 6997 omega/cm2.
