Abstract

A method of electrodepositing a decorative nickel/chromium coating on a metal substrate, which comprises, as its essential step, before a final chromium plating step, electroplating on the substrate a nickel layer containing fine particles of a solid, non-conductive material embedded therein. Improved results are achieved when the nickel layer is electroplated from an aqueous nickel-plating bath containing dispersed therein from 0.1 to 10.0 g/l of microcrystalline particles of a nickel compound, which is insoluble in the bath, selected from the group consisting of the compounds having the formula Nix [M(CN)yAz] and compounds having the formula Nix[M(SCN)y] wherein M is a transition metal, A is NO2<-> or CO, z is 0 or 1, y+z is the coordination number of the transition metal, and x is the number of nickel atoms saturating the valence of the complex portion of the nickel compound.
