Electrodeposition of decorative chromium is the principal means of imparting the physical and chemical properties of chromium to the surface of less expensive and easier-to-form materials such as steel and plastics. The most desirable properties of chromium as a metal coating are its inherent protective and decorative characteristics. The deposit's high reflectivity is retained in service because of chromium's excellent tarnish, corrosion, wear, and scratch resistance. Decorative chromium is almost exclusively plated over a nickel electrodeposit, which Can easily be plated over substrates such as plastics, steel, aluminum, copper alloys, and zinc Die castings.
