Decorative chromium electroplating has been successfully used for more than 80 years. The majority of chromium platers use electrolytes based upon chromium trioxide and sulphuric acid, which have remained the default systems for many decades. The term "chromium plate" is used to define more than just a single metallic deposit; chromium electroplating refers to a multi-layer deposit consisting of a copper and/or nickel undercoat and thin chromium top coat. The function of the chromium layer is to provide a strong, powerful, and effective anti-tarnish to the bright nickel coating. Today, chromium electroplating is carried out on many different and varied components, including automotive bright exterior trim and alloy wheels, sanitary and bathroom fittings, tubular furniture, point of sale equipment (shop fittings), and consumer electronic goods.
