电沉积泡沫镍的DTR控制研究

Control of DTR for Ni Foam Fabricated by Electrodeposition Technique

研究电解液的组成和电沉积过程对电流密度的影响,指出决定厚尺度泡沫镍沉积厚度比(DTR)的决定因素是电流密度的控制,而电解液的电导率及主盐浓度也有重要影响。

The mechanical properties of the thick Ni foam prepared by electrodeposition technology are not homogeneous from the surface to the middle section due to the different Ni deposit thicknesses on the ligament of PU foam, resulting in a larger deposition thickness ratio （DTR）. In this study, the effects of the constitution of electrolyte and the current density during electrodepositing process on the DTR of thick Ni foam were investigated. The results show that the current density has the predominant effects; and the conductivity of electrolyte and the concentration of main salt are also the important factors.
