Nanocrystalline nickel-tungsten (Ni-W) coatings was obtained by pulse electrodeposition in the plating bath with and without containing β-cyclodextrin (β-CD). The mirco-structure and morphologies of coatings were characterized by energy dispersive spectrometer (EDS), X-ray diffraction (XRD) and scanning electron microscopy (SEM). It was found that smaller grain size and more compact surface structure can be realized by introduction of β-CD, which had no influence on the compositions of the
