Solution 1
In electroplating, the deposition of a metal layer on a material occurs. This process involves using an electric current to reduce dissolved metal cations, which allows them to form a thin coherent metal coating on an electrode. The term is also used for electrical oxidation of anions on to a solid substrate. This is done to decorate objects, for corrosion inhibition, to improve solderability, to harden, to improve wearability, to reduce friction, to improve paint adhesion, to alter conductivity, and for other purposes.
Solution 2
The process that occurs in electroplating is the deposition of a metal layer on a material. This is done by using an electric current to reduce dissolved metal cations, which allows them to form a thin coherent metal coating on an electrode.
