Chrome plating, often referred to simply as chrome, is a technique of electroplating a thin layer of chromium onto a metal object. The chromed layer can be decorative, provide corrosion resistance, ease cleaning procedures, or increase surface hardness.
A component to be chrome plated will generally go through these different stages:
degreasing to remove heavy soiling;
manual cleaning to remove all residual traces of dirt and surface impurities;
various pretreatments depending on the substrate;
placement into the chrome plating vat, where it is allowed to warm to solution temperature; and
application of plating current, under which the component is left for the required time to attain thickness.
