“…Notably, the Ni electrodeposit on Cr/C multilayered film substrate was seen to have a relatively refined-grain structure with a more uniform size distribution, which was in correlation with the growth characteristic of instantaneous nucleation mode. In this instance, the higher electrical conductivity enhanced the electric field surrounding the Cr/C film interface, and accelerated the mass transfer between the electrode and electrolyte, thereby increasing the initial anchoring of active sites necessary for the deposition of carbon matrix [35].…”

The Ni electrodeposition combined with multilayered structure film is a promising strategy in modern optical manufacturing, while less effort has been devoted to comprehending the electrochemical reaction process, which is essential for their practical applications. In view of this, the initial reduction dynamics and nucleation mechanisms of Ni electrodepositions on multilayer W/Si and Cr/C films were analyzed in this work, and the morphological, crystal, and mechanical characteristics of produced Ni electrodeposits were further determined and compared. The results show that the considerably irregular crystals accompanied by high tensile stress of 119.5 MPa were formed for the Ni electrodeposit on W/Si film, which were mainly attributed to the progressive nucleation process with more severe side reaction of hydrogen evolution. By contrast, the instantaneous nucleation mode with lower reduction resistance were revealed for the Ni electrodeposition on Cr/C film, which presented a comparatively fine–grained texture, less roughness, and smaller stress structure. To summarize, the more stable electrochemical reaction process and improved structure uniformity are obtained for the Ni electrodeposition on metal/C–based film, which offers a theoretical guidance for optimized fabrication of multilayer optical devices in extreme ultraviolet, X–ray, and neutron focusing fields.

A kind of wear-resistant diamond-like carbon (DLC) films doped with Ni, N, and multiwalled carbon nanotubes (MWCNTs) are synthesized on Ti-6Al-4V titanium alloy by a combined method of pulsed electrodeposition and liquid-phase electrodeposition. The effect of different concentrations of MWCNTs on the microstructure and friction mechanism of Co-DLC films is investigated. The results show that the polydimethyl diallyl ammonium chloride (PDDA)-MWCNTs complex tend to deposit parallel to the substrate. Benefiting from the "bridging" effect of the MWCNTs between the cluster structures, it effectively reduces the protrusions on the surface of the films. When the concentration of MWCNTs is 0.06 g L À1 , the surface microstructure of the films is uniform and dense, and the films present a low I D /I G value (0.57) and a high sp 3 -C content. The Raman and X-ray photoelectron spectroscopy patterns reveal that the Ni/N/MWCNTs-DLC films are typical amorphous carbon films. Furthermore, the micro-indentation hardness of the Co-DLC films reaches 513.24 HV. The lubricated Ni/N/MWCNTs-DLC films significantly improve the frictional wear properties of the titanium alloy surface, which is mainly attributed to the homogeneous and dense structure and the low friction coefficient (0.146) and wear loss (1.40 Â 10 À5 kg m À1 ).
