Hint: Electroplating is the method of using an electro-deposition process to apply a metal coating to another piece of metal (or another conductive surface). The deposited metal in electroplating becomes a part of the current commodity after plating/coating.

Complete answer:
Electroplating is the method of using an electro-deposition process to apply a metal coating to another piece of metal (or another conductive surface). The deposited metal in electroplating becomes a part of the current commodity after plating/coating.
Electroplating is commonly used in industry and the decorative arts to increase object surface properties such as abrasion and corrosion resistance, lubricity, reflectivity, electrical conductivity, and appearance. It may also be used to increase the thickness of undersized or worn-out pieces, as well as to electroform metal plates with complex shapes. It's also used to clean metals like copper.
Occasionally, the term "electroplating" is applied to procedures that use an electric current to produce an oxidation of anions on a solid substrate, such as the formation of silver chloride on silver wire to create silver/silver-chloride electrodes.
Electroplating cannot plate any plastic because:
As we all know, electroplating is a procedure in which one metal is coated with another metal. Plastic isn't really close to being a metal.
In electroplating, the coated material must be a strong electrical conductor. Plastic, on the other hand, is a poor conductor of electricity.
As a result, electroplating cannot be used to layer plastic on metal.

Note:
The chemical, electrical, and mechanical properties of the workpiece are all altered by electroplating. As nickel plating increases corrosion resistance, this is an example of a chemical transition. A change in external appearance is an example of a physical alteration. A change in tensile strength or surface hardness, which is a necessary trait in the tooling industry, is an example of a mechanical change. Acid gold electroplating on copper or nickel-plated circuits lowers contact resistance and increases surface hardness. If case hardening of such areas is not required, copper-plated mild steel areas serve as a mask. Tin-plated steel is chromium-plated to prevent tin oxidation from dulling the surface.
