AP-42, CH 12.20: Electroplating

ElectroplatingThis section addresses the Electroplating industry. However, emphasis is placed on chromiumelectroplating and chromic acid anodizing because the majority of emissions data and otherinformation available were for this area of the Electroplating industry. Detailed information on theprocess operations, emissions, and controls associated with other types of Electroplating will be addedto this section as it becomes available. The six-digit Source Classification Code (SCC) forelectroplating is Process Description1-4 Electroplating is the process of applying a metallic coating to an article by passing an electriccurrent through an electrolyte in contact with the article, thereby forming a surface having propertiesor dimensions different from those of the article. Essentially any electrically conductive surface canbe electroplated. Special techniques, such as coating with metallic-loaded paints or silver-reducedspray, can be used to make nonconductive surfaces, such as plastic, electrically conductive forelectroplating.

dislodge surface soil with inorganic cleaning solutions, such as sodium carbonate, sodium phosphate, or sodium hydroxide. Acid dipping, which is optional, is used to remove tarnish or oxide films ... followed by strike plating of copper, copper electroplating, nickel electroplating, and chromium electroplating.
