Selective Plating Metal Finishing

This process is known as selective or brush plating. It has also been known as swab or contact plating and various other descriptive names. The plating tool consists of an insulated handle on which an anode, usually made from graphite, is molded. The anode is covered with an absorbent material which holds the solution. Two electrical leads connect from the terminals of a D.C. rectifier to the plating tool and part. When tool and part make contact, the circuit is closed. As the current flows, metal ions from the solution are deposited onto the part forming a molecular bond. The plate applied has all the characteristics provided by immersion plating, but can be selectively applied. Used for both repairs and plating on parts too large for standard tank immersion.
