When the plating process occurs, the metal (chrome) reduces onto the base metal of the part being plated. 0000005642 00000 n The different types of electroplating are: mass plating (also barrel plating), rack plating, continuous plating, and in line plating. To see all these, you have to get the spec ASTM B-633. There are many different types of metal plating and in it’s simplest definition, metal plating is a thin covering of metal on top of another metal. Electroplating is a process that uses chemical or electrochemical method to form a coherent metallic coating layer on the surface of base materials. 0000001485 00000 n C.-J. A higher service condition (seen as SC1 to SC4) means the part will be exposed to a harsher environment and thus will require a thicker plating to keep the host part from corrod-ing. Thickness of the plating is denoted as the service con-dition of the part. Corrosion resistance is very good, especially with TYPE II finish. Electroplating can be further classified by the type of metal that is used to provide the coating. The electroplating is mainly used for decorative purposes or to prevent corrosion.
