The effect of supercritical carbon dioxide emulsion (Sc-CO2-E) on the smooth and microhardness of nickel film electroplated using Watts bath was studied in this paper. Morphology of nickel film electroplated with Sc-CO2-E was found much uniform. Microhardness of nickel film electroplated with Sc-CO2-E was higher than that of nickel film electroplated through conventional method. A increasing of microhardness was found for nickel film electroplated through Sc-CO2-E when increasing experimental pressure from 12 to 18 MPa, and the smooth of nickel film be promoted. This was because of higher hydrogen solubility and higher mobility in Sc-CO2-E. Grain size of nickel film electroplated with Sc-CO2-E was found to be refinement.
