ElectroplatingWikipedia
Electroplating is a general name for processes that create a metal coating on a solid substrate through the reduction of cations of that metal by means of a direct electric current.The part to be coated acts as the cathode negative electrode of an electrolytic cell; the electrolyte is a solution of a salt of the metal to be coated; and the anode positive electrode is usually either a block

Michael Faraday's gold colloidsThe Royal Institution
These liquids are the first examples of metallic gold colloids. They were made, accidentally, by Michael Faraday whilst he was mounting thin sheets of gold leaf onto microscope slides.. Faraday spent a significant amount of time in the mid 1850s investigating the properties of light and matter.

Electroplating vs electroforming: what's the difference?
Jul 04, 2017The electrolytic bath is used to deposit metal for example nickel, gold or copper onto a conductive patterned surface. Fig.1: The electroforming process In electroforming, the metal can be grown as thick as the customer wants. In the industry, the model on which the metal is built is called a mandrel.

Gold Platingan overviewScienceDirect Topics
Currently, electrolytic gold plating is done using [AuCN 2]or, to a lesser extent, [AuSO 3 3] 3, usually as the potassium salt. Baths have been formulated using acidic, neutral, and basic solutions to which agents are added to tie up impurities and to brighten, harden, and control the metal grain size.
