| Abstract: | Nickel-tungsten alloy eletrodeposits have been adopted as chromium substitute coatings for surface treatment for their high hardness and excellent wearability and corrosion resistance.The purpose of the study was to investigate the mechanism of nickel-tungsten electrodeposition.The cyclic voltammetry characteristics and initial behavior of nickel-tungsten alloy on glass carbon electrode were studied by means of cyclic voltammetry and potentiostatic step. Tungstate ions were reduced to oxide with intermediate valence. The results show that the existence of tungstate has great restraint action on cathodic hydrogen evolution. The electrodeposition of nickel-tungsten alloy performs as instantaneous nucleation followed by three dimensional growth. |
