Abstract
Experiment was designed to conduct cathode plasma electrodeposition. In the experimental cathode plasma electrodeposition of nickel, ethanol and citric acid at various concentrations along with different electrolytes were adopted to study the effect of electrolyte composition on the deposition rate and surface appearance of a nickel electrodeposition layer. The results revealed that, as the ethanol concentration of an electrolyte increased, the deposition layer of nickel gradually exhibited smoother surfaces as well as uniform, fine structures thereon. In addition, the concentration enrichment of the; in the electrolytes visibly improved the deposition rate of nickel and decreased the particle size of the deposition layer. Besides, when nickel chloride or nickel sulphate were used as the main salts, the deposition rate of nickel was higher, while it was lower when nickel aminosulphonate was used as the main salt. Additionally, the differences in the three types of main salts exerted a slight influence on the surface appearance of nickel electrodeposition layers.
