Decorative chrome is typically applied directly over bright nickel. The deposit is very thin usually ranging from coverage to 50 micro-inches. The coating function will prevent the oxidation of the nickel, allow additional corrosion protection and improve wear of the plating as well as form a more pleasing blue tint to the final coating.
This coating, when put over bright nickel has a very bright, reflective surface. It is applied to a wide variety of parts ranging from washers to bumpers. All surface defects are magnified with decorative chrome, so to achieve the “mirror” finish, the parts must be polished to a “mirror” finish prior to plating. Decorative chrome generally is not plated directly on the base metal, but will be applied over the top of nickel. When this is done, it can be plated to many types of metals such as aluminum, zinc die cast, brass, copper, steel, and stainless steel.
