NiCo Electroforming Research on Ru/c Multilayer Film for Mirror Production

The metal/C-based multilayer film with high reflectivity is the “workhorse” in today's optical application, and NiCo electroforming offers a promising prospect in contemporary optical production. Therefore, the NiCo electroforming was performed on metal/C-based multilayer film in this study, and the obtained deposition structure and electrochemical mechanism were discussed. The results show that the Ni electrodeposition on Ru/C multilayer film obeyed the three-dimensional (3D) continuous nucleation process under diffusion control, which was in accordance with the crystal growth characteristics. This work confirmed the feasibility of direct NiCo electroforming on Ru/C multilayer film, and provided a theoretical backing for the fabrication of metal/C-based multilayer mirror.
