By now it should be evident that electrodeposition or electroplating should be defined as the process in which the deposit of a (usually) thin layer (of metal) is formed "electrolyticly" upon a substrate (that is often, but not always, also a metal).
In the case of electroplating, judicial placement of the anode(s) as well as modifications of the current density are required to overcome the thickness irregularity effects.

Electroplating is the deposition of a metallic coating onto an object by putting a negative charge onto the object and immersing it into a solution which contains a salt of the metal to be deposited.
The metallic ions of the salt carry a positive charge and are attracted to the part.

 Understanding decorative electroplating
Electroplating is a process used to apply a new metal surface coating over a substrate or base material of either metal or ABS plastic.
Based on the principles of electrolysis, electroplating involves transfer of metal from an ‘anode’ to the surface of an item via the application of electric current travelling to the ‘cathode’ whilst suspended in an ‘electrolyte’ (a liquid solution of substances which enable the transfer).
The nature of electroplating therefore demands that some consideration be given to the impact on achieving a desired surface quality from different shapes and designs.

 Damascene copper electroplating for chip interconnections
Electroplating occurs only on those areas of the seed layer that are not covered by the mask.
Damascene electroplating is ideally suited for the fabrication of interconnect structures, since it allows inlaying of metal simultaneously in via holes and overlying line trenches [12] by a process called dual damascene (Figure 2).
Further, it is compatible with the requirement for a barrier layer between the seed layer and the insulator; the barrier prevents interaction between the metal and the insulator [13].

 [Ganoksin] Electroplating & Electropolishing of Jewellery
Electroplating is a method to put a metal coating onto an object, in our case a piece of jewellery, by placing it in a solution containing the metal to be plated and passing an electrical current through the piece and the solution.
Electroplating is a comparatively quick and easy process to carry out and does not require major investment in costly equipment.
Often, in electroplating, we use an inert anode, where metal is not dissolved away, and control the concentration of the depositing metal in the electrolyte solution by direct additions of the appropriate metal as a salt to the electrolyte.

A wide variety of metal components are transported from the original manufacturing location to an electroplating facility to be coated with specific metals to improve the appearance, resistance to corrosion, or engineering performance.
Metal components are cleaned, etched, electroplated and finished by dipping into a series of vats containing a combination of corrosive, metal and/or cyanide containing chemical solutions.
The metal and cyanide containing salts are usually received as bagged or containerized solids, or drummed liquids, which are dissolved or diluted into large plating vats.

 Electroplating
The electroplating of metals is generally carried out in order to improve the appearance or corrosion resistance of a surface by electrodepositing a thin layer of some desired metal on it.
In electroplating, the plating metal is generally the anode, and the object to be plated is the cathode.
The cell used in electroplating contains an electrolyte which is usually but not always an aqueous solution containing a reasonably high concentration of an ion of the metal which is to be electroplated on to the surface.

 Process for direct zinc electroplating of aluminum strip - Patent 5234574
Consequently, when zinc electroplating is applied to aluminum strip in a continuous plating line in which the aluminum strip is pretreated by the above-described method prior to the desired electroplating, it is impossible to attain a high line speed and a high efficiency as realized in a similar continuous electroplating line for steel strip.
If a continuous electroplating line for aluminum strip having a line speed as high as that employed in electroplating of steel strip is constructed, it will have a line length which is several times as long as the length of an electroplating line for steel strip.
Similarly, the terms "zinc electroplating", "zinc plating", and "zinc plated coating" used herein refers to electroplating or electroplated coating with either zinc or a zinc alloy.

Controlling the thickness of the electroplated object is generally achieved by altering the time the object spends in the salt solution.

Electroplating is a process used to apply very thin coatings of metal onto objects of various kinds.
Electroplating became an important commercial process in the 1840s, when John Wright of Birmingham, England, discovered that gold or silver could be dissolved in potassium cyanide for use in electroplating.
For many years electroplating was used mainly to produce expensive-looking objects from inexpensive materials.

 Electroplating of Plastics
However, it was soon established that only electroplated nickel/chromium would give the necessary quality that was related not only to aesthetic appeal but also to other properties of this particular coating system - good resistance to corrosion, good resistance to abrasion, and ease of cleaning.
The basic problem in attempting to electroplate onto plastics substrates is, of course, that they are electrically non-conductive and cannot be immersed in a plating solution and coated in the way that metal objects can.
However, it was subsequently shown that the thickness of nickel required on plastics substrates is similar to that necessary on metallic ones to prevent corrosion of the thick copper undercoat.
