What You Need to Know About Thin-Film Coating
What are Physical and Chemical Vapor Deposition (PVD and CVD)?
PVD thin-film coating is a process in which a solid material, often a metal, is vaporized in a vacuum and deposited, atom by atom, onto the surface of a part. The material may be combined with nitrogen, oxygen, or a carbon-containing gas to form compound materials. This process forms a thin, bonded, metal or metal-ceramic layer on your part or product’s surface that greatly improves its appearance, durability, and performance. The deposition process is adjusted to change the color, durability, or other characteristics of a coating.
PECVD (plasma-enhanced chemical vapor deposition) vacuum coating is a similar process in which the atoms in a gas are energized and deposited on a surface. Diamond-like carbon (DLC) is an example of a thin-film coating deposited using a PECVD process.

How do VaporTech systems work?
PVD and DLC PECVD coatings are deposited using a thin-film deposition system. VaporTech systems consist of a vacuum chamber, pumping system, and power supplies that drive the deposition process. A batch of parts are loaded into the vacuum chamber and coated in a fully automated process. Once a thin-film coating is applied, parts may go directly to assembly or packaging. Systems are available in multiple sizes to coat small or large volumes of different size parts (up to 1.2 meters or 48 inches). Both metal and plastic parts can be coated using unique VaporTech low-temperature processes.
