ELECTRO-PLATING: BASICS The following section would like to explain the physical and chemical basis for electroplating to the extent as it is useful for understanding the following chapters. The Metal Potential A Metal in Aqueous Solution If a metal is dipped in an aqueous solution a salt solution a diluted acid or only water some of the
Copper plating and copper sheathing were widely used to protect the under-water hulls of ships a technique pioneered by the British Admiralty in the 18th century. The Norddeutsche Affinerie in Hamburg was the first modern electroplating plant starting its production in 1876.
Plating is a surface covering in which a metal is deposited on a conductive surface. Plating has been done for hundreds of years; it is also critical for modern technology. Plating is used to decorate objects for corrosion inhibition to improve solderability to harden to improve wearability to reduce friction to improve paint adhesion to alter conductivity to improve IR reflectivity ...
Cooper Plating offers an electroplating process that encompasses several metal plating solutions. We offer gold silver copper nickel electroless nickel tin and passivation. Each type of metal plating is used to achieve specific objectives which can range from building up worn parts to increasing bondability or solderability.

Plating with zinc is a relatively recent process and it did not gain widespread use until approximately 1980. Prior to that time cadmium was the preferred metal for electroplating in appli ions where maximum protection against corrosion was required.
