Pulse Electrodeposited Nanocrystalline Ni-W-Fe-La Alloys as Hydrogen Electrocatalytic Materials
Nanocrystalline Ni-W-Fe-La alloys coatings were prepared by pulse electrodeposition. X-ray diffraction (XRD), scan electron microscopy (SEM) and energy dispersive spectrometer (EDS) were used to characterize the products, which average particle size of 17 nm and have special properties such as array densification, uniformity and crack-free surface. The linear sweep voltammetry (LSV) and neutral salt spray test demonstrated the coatings have good catalytic activity for hydrogen evolution and corrosion resistance.
