Galvanic plating process
WebElectroplating is a process that uses an electric current to reduce dissolved metal cations so that they form a thin coherent metal coating on an electrode. Electroless plating , also known as chemical or auto-catalytic plating , is a non-galvanic plating method that involves several simultaneous reactions in an aqueous solution, which occur ...

WebThe nickel plating consists in coating the article with a thin layer of nickel protective film, which protects the product from the same rust and dullness. Nickel plating gives the object more “vintage” than the chrome plating, with the color tending to the yellow. On the contrary, it is also possible to carry out nickel free treatments, mainly intended for the … WebThe plating process starts with a gold strike treatment to prevent the exchange reaction. The same strike bath can be used for the first rinse after the gold plating. The current density depends a lot on the processing method; that is, 0.2–0.4 Adm −2 is used for barrel plating and 0.5–1 Adm −2 for rack plating.
