1837 lithographic portrait of Moritz von Jacobi (1801–1874), who invented electrotyping in 1838.. At present, most sources credit Moritz Hermann Jacobi with the invention of "galvanoplasty" or electrotyping in 1838; Jacobi was a Prussian scientist who was working in St. Petersburg, Russia.
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.
Nickel electroplating is a process of depositing nickel onto a metal part. Parts to be plated must be clean and free of dirt, corrosion, and defects before plating can begin. [3] To clean and protect the part during the plating process, a combination of heat treating, cleaning, masking, pickling, and etching may be used. [1]
Electroplating is a common surface-treatment technique. It involves bonding a thin layer of another metal such as gold , silver , chromium or zinc to the surface of the product by hydrolysis. It is used to reduce corrosion, create abrasion resistance and improve the product's aesthetic appearance.
Such zinc electroplating or zinc alloy electroplating maintains a dominant position among other electroplating process options, based upon electroplated tonnage per annum. According to the International Zinc Association, more than 5 million tons are used yearly for both hot-dip galvanization and electroplating. [ 1 ]
Electroplating – a process where a thin layer of metal is deposited onto the surface of an object using an electric current; Electrochemical cells – generates electrical energy from chemical reactions; Electrotyping – a process used to create metal copies of designs by depositing metal onto a mold using electroplating
Zinc phosphate is an inorganic compound with the formula Zn 3 (PO 4) 2.This white powder is widely used as a corrosion resistant coating on metal surfaces either as part of an electroplating process or applied as a primer pigment (see also red lead).
