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.
Electrophoretic Deposition Process. Electrophoretic deposition (EPD), is a term for a broad range of industrial processes which includes electrocoating, cathodic electrodeposition, anodic electrodeposition, and electrophoretic coating, or electrophoretic painting.
Alkaline cyanide baths have historically been one of the most commonly-used plating chemistries for copper electrodeposition. [5] [8] Cyanide copper baths typically provide high covering and throwing power, allowing uniform and complete coverage of the substrate, but often plate at lower current efficiency. [2]
Metal powder production by electrodeposition is included in this category, or sometimes electrowinning, or a separate category depending on application. [2] Electroplating, the deposition of a layer of one metal on another [2] Electroforming, the manufacture of, usually thin, metal parts through electroplating [2]
Electrodeposition may refer to: Electroplating , a process that uses electric current to reduce dissolved metal cations so that they form a coherent metal coating on an electrode Electrophoretic deposition , a term for a broad range of industrial processes which includes electrocoating, e-coating, cathodic electrodeposition, anodic ...
The electroless deposition and electroplating bath actively performs cathodic and anodic reactions at the surface of the substrate. [2] [3] The standard electrode potential of the metal and reducing agent are important as a driving force for electron exchange. [3] The standard potential is defined as the power of reduction of compounds.
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 ...
There are various important electrochemical processes in both nature and industry, like the coating of objects with metals or metal oxides through electrodeposition, the addition (electroplating) or removal (electropolishing) of thin layers of metal from an object's surface, [33] and the detection of alcohol in drunk drivers through the redox ...
