Abstract

The surface roughness, microhardness, crystal structure and corrosion performance of nickels electroplated at atmospheric pressure and in supercritical CO₂ fluid, respectively, are compared. The experimental results showed that nickel electroplated in the latter case exhibited a lower surface roughness and a higher hardness. In HCl solution, the nickel deposited in supercritical CO₂ fluid had a lower anodic current density and a higher polarization resistance. The advantage of emulsified supercritical CO₂ fluid for electroplating was demonstrated.
