Abstract:

The characteristics of CO2-supercritical fluids (SCF-CO2) and the features of SCF-CO2 electroplating technology are analyzed. The effects of surfactant additive content, CO2 volume fraction, as well as temperature, pressure and other operating parameters of SCF-CO2 electroplating on the preparation of nanomaterials are reviewed. The plated nanomaterial films using this new method have a uniform surface and dense structures, which are better than the materials obtained by conventional electroplating methods. The micro-hardness and wear resistance are also increased significantly. At last, the directions of development of SCF-CO2 electroplating technology in future are expected.
