The Norddeutsche Affinerie in Hamburg was the first modern electroplating plant starting its production in 1876. [23] As the science of electrochemistry grew, its relationship to electroplating became understood and other types of non-decorative metal electroplating were developed.
This can be especially complex because non-cleaning steps may be integrated in such plants like application of corrosion protection layers or phosphating. Cleaning can also be simple: the cleaning processes are integrated into other processes, as it is the case with electroplating or galvanising, where it usually serves as a pre-treatment step.
Copper electroplating is the process of electroplating a layer of copper onto the surface of a metal object. Copper is used both as a standalone coating and as an undercoat onto which other metals are subsequently plated. [ 1 ]
In electrowinning, an electrical current is passed from an inert anode through a leach solution containing the dissolved metal ions so that the metal is recovered as it is reduced and deposited in an electroplating process onto the cathode. In electrorefining, the anode consists of the impure metal (e.g., copper) to be refined. The impure ...
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 galvanizing and electroplating. [ 1 ]

From January 2008 to April 2009, if you bought shares in companies when William R. Howell joined the board, and sold them when he left, you would have a -37.8 percent return on your investment, compared to a -41.7 percent return from the S&P 500.
electroplating – coating the metal surface with another metal using electrolysis. patination – chemically reacting the metal surface to form a colored oxide or salt. [1] anodizing – electrolytic passivation process used to increase the thickness of the natural oxide layer, producing a porous surface which can accept organic or inorganic ...
