Production and Structure of Ni-W and Ni+W Coatings

Abstract:

The Ni-W alloy coatings and Ni+W composite deposits were prepared by the electrodeposition under the galvanostatic conditions at the deposition current density of j_dep = -300 mA cm^-2. The surface morphology and chemical composition of the coatings were examined using a scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS), respectively. Phase composition investigations were conducted by X-ray diffraction (XRD) method. It was found that introduction of tungsten powder into nickel matrix allowed to obtain the Ni+W composite coating with very rough surface as compared with the smooth Ni-W alloy coating. Thus obtained Ni+W porous coating may be useful for the need of hydrogen technologies.
