Effect of Saccharin Addition on the Electrodeposition of Nickel from a Watts-Type Electrolyte
The influence of saccharin addition on cathodic polarization, cathodic current efficiency, hardness, surface morphology, and internal stress of nickel electrodeposition from a Watts-type plating bath was studied in this work. The results show that the addition of saccharin may enhance the cathodic polarization, modify the surface morphology, increase the hardness, and decrease the tensile stress. In particular, when the concentration of saccharin is 0.4 g/L, the surface of nickel deposition is smoothest. When the concentration of saccharin is 0.05 g/L, the hardness of nickel deposition is highest.
