What does plating mean?
Plating is a thin layer of metal applied to another material, commonly to improve its appearance, protect it from wear or corrosion, or give it a reflective surface. Silver plating, gold plating, and chrome plating are familiar examples. The word can also mean the process of applying such a coating, as in the plating of electrical components or industrial parts. In vehicle, naval, and military contexts, plating may refer collectively to metal plates used as protective armor or structural covering. Although “plating” can suggest a costly or decorative finish, it is also a practical industrial term. It is distinct from “plate,” which denotes an individual flat piece of metal rather than the coating or the application process.

Where does plating come from?
Plating was formed in English from plate with the suffix -ing. The word plate entered Middle English through Old French and ultimately has roots associated with the broad, flat meaning of Latin plattus. The related word platter developed through the same general culinary and metalware tradition, while modern plating continues the older sense of covering an object with a metal plate or layer.
