What does metallization mean?
Metallization is the technical term for applying metal to the surface of another material, often as a thin protective or functional layer. It is used in manufacturing, engineering, electronics, and materials science, where coating a surface with metal can improve resistance to corrosion, improve conductivity, or create other desired properties. The word can also refer more broadly to making a substance metallic. In ordinary conversation, people are more likely to say "metal coating" or "plating," but metallization is especially useful when discussing a technical process or treatment. The term is normally uncountable, as in "the metallization of the steel," and is generally more formal and specialized than everyday descriptions of adding metal to an object.
The process of covering a surface or material with a layer of metal.
"The product line uses metallization to protect the components from corrosion."
Common in technical and industrial contexts; usually uncountable.
The conversion of a substance or material into a metallic form.
"The study focuses on the metallization of polymer films."
The plural is uncommon; the uncountable form is normally preferred for the process. A plural may be used for separate instances or treatments.
"The factory performed several metallizations on the components."
Metallization is the thin, transformative art of giving a surface a distinctly metallic identity.

Where does metallization come from?
Metallization was formed in the 19th century from "metallize" and the suffix "-ation." The verb in turn comes through French from Latin "metallum," meaning metal, which was borrowed from Greek "metallon." The same ancient root underlies related English words such as metallurgy, metallic, and mettle.
