Microstructure and Electrochemical Properties of Foamed Ni-Mo Alloy by Pulse-Electrodeposition
A variety of foamed Ni-Mo alloys coatings have been obtained using pulsed electrodeposition technique. The deposit is mainly composed of amorphous structural through the X-ray diffractions (XRD), the morphology clearly contains large amounts of multi-bubble pore structure with pentagonal or hexagonal skeleton structure and obviously stratifys through scanning electron microscopy (SEM) experimentals. This pentagonal or hexagonal skeleton structure and obvious stratification has a larger surface area. The electrolysis experiments show that such foamed alloys have a low hydrogen evolution overpotential and a better corrosion resistance in 25°C, 7mol·L-1 KOH alkaline solution.
