Abstract
A process for forming a decorative chromium plating on a plastic substrate includes depositing an electrically conductive coating on the plastic substrate, electrodepositing on the electrically conductive coating a high leveling semi-bright nickel electroplate layer, electrodepositing on the high leveling semi-bright nickel electroplate layer a bright nickel electroplate layer, and electrodepositing over the bright nickel electroplate layer a chromium electroplate layer. An advantage of the process is that a lustrous decorative chromium plating having good corrosion resistance and thermal cycling characteristics is obtained without a copper sublayer, and while using relatively thin nickel sublayers.
