Thick chrome plating, also known as hard chrome plating or electroplating, is a process of surface coating of chromium on a metal part. Deposition occurs by electroplating and, therefore, electric current is used to finalise the treatment.
Electroplating takes place inside tanks (or electrolytic cells), where the component is immersed in a specially formulated solution.
A variety of materials can be subjected to the process, including iron, steel, copper and brass.
