Hydrogen evolution assisted electrodeposition is a new bottom-up technique allowing the fast and simple synthesis of nanometals. Electrochemical dealloying is a top-down approach with the same purpose. In this work, we show that a combination of these two methods in sequence by pulse-reverse electrodeposition can be used to prepare high-surface-area nanostructured metals. Highly porous adherent...

5 wt % Co, are of both theoretical research and practical interest due to the anomalous codeposition behavior, the preferential deposition of less noble metal, and to the material's low coefficient of thermal expansion, CTE. A better understanding of anomalous codeposition allows for controlling the deposition rates of individual Fe, Ni, and Co metal during codeposition and hence the compositio...

In this study, using 45# carbon steel as the substrate, a first experimental analysis was carried out on polarisation behaviour of different component wattage plating solutions in order to determine reasonable content nanodiamond particles nickel/nanodiamond composite solution. Secondly, effect double-pulse forward and reverse duty cycle working time performance then investigated by testing thi...

Cu–Al2O3 composite coatings were prepared in the use of pulse jet electrodeposition technology. Pulse current parameters including duty cycle and frequency researched about their effects on microstructure variation Al2O3 nanoparticles content coating. The mechanical properties anti-corrosion resistance coating examined. results show that properly decreasing raising are able to generate a compac...
