electroless plating

electroless plating
/i lek"troh lis/
a technique of plating metal by chemical rather than electrical means, in which the piece to be plated is immersed in a reducing agent that, when catalyzed by certain materials, changes metal ions to metal that forms a deposit on the piece.
[ELECTRO- + -LESS]

      nonelectrical plating of metals and plastics to achieve uniform coatings by a process of controlled autocatalytic (self-continuing) reduction. Discovered in 1944 by A. Brenner and G.E. Riddell, electroless plating involves the deposition of such metals as copper, nickel, silver, gold, or palladium on the surface of a variety of materials by means of a reducing chemical bath. It is also used in mirroring (mirror), in which a clean surface of glass is dipped into an ammoniacal silver solution mixed with Rochelle salt or with a nitric acid–cane-sugar alcohol solution. Nonmetallic surfaces, such as plastics (plastic), must be chemically treated prior to electroless plating. The major expansion of electroless plating has come in the area of plastics, as in the plating of printed electronic circuits. A large number of consumer goods are coated by this method to create durable and attractive surfaces.
