Immersion silver plating (or IAg plating) is a surface plating process that creates a thin layer of silver over copper objects. It consists in dipping the object ...
Plating is a finishing process in which a metal is deposited on a 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, for ...
Electroplating, also known as electrochemical deposition or electrodeposition, is a process for producing a metal coating on a solid substrate through the reduction of cations of that metal by means of a direct electric current.
Whether silver plating or pure silver, the composite of the metal will tarnish when exposed to air and sulfur. Tarnish is a chemical reaction on the surface of metal (copper, brass, silver, etc.) and causes a layer of corrosion. In the case of silver tarnish, the silver combines with sulfur and forms silver sulfide (Ag 2 S), which is black.
After the modern process for the production of electroplated nickel silver was patented in 1840 by George Richards Elkington and his cousin Henry Elkington in Birmingham, the development of electroplating caused nickel silver to become widely used. It formed an ideal, strong and bright substrate for the plating process.
OSP Pair of table salts, the interiors gilded to prevent corrosion. 'Bleeding' of the copper can be seen on the rims. Old Sheffield Plate (or OSP) is the name generally given to the material developed by Thomas Boulsover in the 1740s, a fusion of copper and sterling silver [1] which could be made into a range of items normally made in solid silver.
