The cathodic process results in considerably more gas being trapped within the film than the anodic process. Since the gas has a higher electrical resistance than either depositing film or the bath itself, the amount of gas has a significant effect on the current at a given applied voltage. This is why cathodic processes are often able to be ...
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.
Chemical Bath Deposition has a long history but until recently was an uncommon method of thin-film deposition. [1]In 1865, Justus Liebig published an article describing the use of Chemical Bath Deposition to silver mirrors (to affix a reflective layer of silver to the back of glass to form a mirror), [5] though in the modern day electroplating and vacuum deposition are more common.
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.
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]

In some cases, the activation step is done in the chromium bath. The chromium bath is a mixture of chromium trioxide and sulfuric acid, the ratio of which varies greatly between 75:1 to 250:1 by weight. This results in an extremely acidic bath (pH 0). The temperature and current density in the bath affect the brightness and final coverage. For ...
