The materials which are being deposited are the major determining factor in the actual processing conditions and equipment which may be used. Due to the wide utilization of electrophoretic painting processes in many industries, aqueous EPD is the most common commercially used EPD process.
The pulse electroplating or pulse electrodeposition (PED) process involves the swift alternating of the electrical potential or current between two different values, resulting in a series of pulses of equal amplitude, duration, and polarity, separated by zero current. By changing the pulse amplitude and width, it is possible to change the ...
Just like in other electrodeposition processes, the ions travel through the solution and deposit on the cathode. [4] [5] The anode efficiency for nickel dissolution is close to 100%, unless the anode becomes passive due to problems with the process, in which case the efficiency drops to 0.
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 ...
Copper plating on aluminium. 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]
Electroforming is a metal forming process in which parts are fabricated through electrodeposition on a model, known in the industry as a mandrel. Conductive (metallic) mandrels are treated to create a mechanical parting layer, or are chemically passivated to limit electroform adhesion to the mandrel and thereby allow its subsequent separation.
Electroless deposition is an important process in the electronic industry for metallization of substrates. Other metallization of substrates also include physical vapor deposition (PVD), chemical vapor deposition (CVD), and electroplating which produce thin metal films but require high temperature, vacuum, and a power source respectively.

Electrometallurgy is the field concerned with the processes of metal electrodeposition. There are seven categories of these processes: Electrolysis; Electrowinning, the extraction of metal from ores [2] Electrorefining, the purification of metals. [2]
