PLATING SILVER METAL FINISHING

When PLATING SILVER, silver cyanide is used in the electrolyte rather than other compounds of silver such as silver nitrate, AgNO3, because the cyanide ion, CN-, reacts with silver ion, Ag+, to form the complex ion Ag(CN) -. This limits the supply of free Ag+ ions in the solution, so they can deposit themselves only very gradually onto the cathode. This produces a shinier and more adherent silver plating.  Silver plating is used for many purposes and applications. 
 

 

SILVER PLATING HISTORICAL INFORMATION

In Ancient civilisations the noble metals were objects of great beauty, believed to be imbued with the mystic qualities of distant heavenly bodies. Classically gold is seen as the symbol of the sun and silver the moon. The ancient Egyptians called silver "white gold."  Some famous attributes of silver are its mythical powers against enchantment and the use of silver bullets, thought to have unique powers against witches and vampires in some cultures.

Historically, silver plate was used to provide a cheaper version of items that might otherwise be made of silver, including cutlery and candlesticks. The earliest kind was Old Sheffield Plate, but in the 19th century new methods of production (including electroplating) were introduced. Sheffield plate is a layered combination of silver and copper that was used to produce a wide range of household articles. These included buttons, caddy spoons, serving utensils, candlesticks and other lighting devices, tea and coffee services, serving dishes and trays, tankards and pitchers, and larger items such as soup tureens and hot water urns. Almost every article made in sterling silver was also crafted by Sheffield makers, who used this manufacturing process to produce nearly identical wares at far less cost.

SILVER PLATING CONSUMER PURPOSES

SILVER PLATED products have the highest conductivity of all metals, can be used for soldering, are corrosion resistant, durable and wear resistant.  Silver Plating is used extensively for a wide variety of consumer purposes.

SILVER PLATING INDUSTRIAL USAGE

In electroplating, plating silver is primarily used for industrial applications.  It is extensively used in the telecom and automotive industries. Another use of Silver plating is for fasteners which are widely used in industry where lubricant cannot be used or where fasteners are assembled into materials where galling is a serious risk. Silver plating is very soft and has very low shear strength, and so acts as a solid lubricant, lowering the coefficient of friction where it is used dry. This means that less torque is required to produce a given level of preload, and this means that a stress is induced in the fastener during tightening. Silver also has the advantage in that it doesn’t oxidise significantly at temperature, making it ideal for exhaust use.

Silver plated nuts are also used in some applications where high loads make it difficult for lubricants to remain in highly loaded parts of the contact. In these instances a low-shear strength coating such as silver can be beneficial. The effectiveness of silver as a lubricant has given rise to a number of silver-doped pastes and greases available commercially.


SILVER PLATING ELECTRONICS

For less demanding applications in electronics, silver plating is often used as a cheaper replacement for gold. (Although silver is a better conductor than gold it does oxidize and so gold is better for contacts. However, variable capacitors are considered of the highest quality when their plates have been silver plated.


SILVER PLATING
JEWELLERY

Solid silver can be quite expensive. For this reason, jewellery is often made of a less expensive base metal and then plated with a thin coating of silver.  Silver plated jewellery is widely used in the costume jewellery market for fashion accessories.   


SILVER PLATING FOR DECORATION

Silver plating is also used for its aesthetic value.  Silver coatings enrich the look and feel of a product adding to the impression of quality.  SILVER PLATING is widely used in the dinnerware industry and for other home ware decoration applications.
