Decorative chromium electroplating has been successfully used for more than 80 years. The majority of chromium platers uses electrolytes based on chromium trioxide and sulfuric 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. However, chromium trioxide has now been reclas-sified as a hazardous substance that may cause cancer. Consequently, the industry now finds itself under intense ressure from international occupational health legislation and corporate demands to reduce the exposure effects of this material to their employees.
