説明

This paper describes the electrodeposition of nickel from Ni(CF3COO)2-NH4Cl-MeOH solutions for studying the electrodeposition mechanism of nickel. Bright and smooth nickel deposits were obtained from Ni(CF3COO)2 500g/l-NH4Cl20.0g/l-MeOH bath under current density of 2.0-22.0Amp/dm2 at 30-50°C. The current efficiencies in this case were about 100% for both of cathode and anode. The rate controlling step of electrodeposition of nickel from Ni(CF3COO)2-NH4Cl 20.0g/l-MeOH bath under current density of 1.0-5.8Amp/dm2 was a charge transfer reaction. The main values in these experiments were as follows: Apparent transfer coefficient: αc=0.75, Apparent valence: n=0.78, Apparent exchange current density: ioc=0.23Amp/dm2, Tafel slope: bc=-0.12V, Apparent activation energy: Ec=5.7kcal/mol.
