A coating is a covering that is applied to the surface of an object, usually referred to as the substrate. Paints and lacquers are coatings that mostly have dual uses of protecting the substrate and being decorative.
Vacuum deposition is a family of processes used to deposit layers of material atom-by-atom or molecule-by-molecule on a solid surface.
Condensing particles can be generated in various ways:
- thermal evaporation, Evaporation (deposition)
Evaporation is a common method of thin-film deposition. The source material is evaporated in a vacuum. The vacuum allows vapor particles to travel directly to the target object (substrate), where they condense back to a solid state. Evaporation is used in microfabrication, and to make macro-scale products such as metallized plastic film.
