Theoretical aspects of electrodeposition of decorative chromium from trivalent electrolytes and corrosion rate study of different nickel/chromium coatings

Abstract The present paper presents a review of theoretical aspects of deposition of chromium from trivalent chromium electrolytes and a corrosion rate study of the initial rate of corrosion of chromium deposits from these electrolytes on nickel deposits. A higher rate of corrosion was obtained from chromium deposits plated from a chloride based electrolyte as compared with a sulphate based electrolyte. No significant difference in corrosion rate was observed when comparing deposits plated from a sulphate based electrolyte with deposits obtained from a standard hexavalent chromium electrolyte.
