Abstract Ni–Cr nanocomposite coatings were prepared by D. C. and pulsed D.C. electroplating technique, respectively, and the contents of Cr in the nanocomposite film was investigated. The results show that the codeposition of Cr nanoparticles in the nanocomposite coating by D.C. electroplating firstly increased with the Cr concentration in electrolyte bath, but the contents of Cr in the film prepared by pulsed D.C. electroplating are higher than those of the D.C. electroplating for the same concentration Cr in the electrolyte bath. The parabolic rate constant for the pulse nanocomposite coating is 2.85 times that of D.C. electroplating films after oxidation at 900 for 24 h, and the corrosion resistance of the pulse nanocomposite coatings is better than that of the D.C. electrodeposited films in Cl ion solution and acid solution. Meanwhile, the microhardness of the pulse nanomcoposite coatings is 2 times that of the D.C. electroplated films. The pulse electrodeposition can reduce the concentration distinction polarization on the surface of the pulse nanocomposite coatings, controll the shut off time, and increase the possibility
of nuclei formation, so the amounts of grain nuclei increase and the perfect nanocomposite coatings with finer grains and more compact structure can be obtained.
