People often ask us: “Just exactly what is PVD coating?” Here’s a brief introduction
You can download our full introductory guide to thin-film finishes (including PVD, CVD, and DLC coating) or more detailed information.
PVD (physical vapor deposition) 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 PVD process forms a thin, bonded, metal or metal-ceramic layer on the surface that greatly improves the appearance, durability, and/or function of a part or product. The deposition process can be easily customized to change the color, durability, or other characteristics of a coating. Related terms are PE-CVD (plasma enhanced chemical vapor deposition) thin-film coating, a similar process in which the atoms in a gas are energized and deposited on a surface. DLC (diamond-like carbon) coatings are a popular example of a thin-film coating deposited using either a PVD or PE-CVD process.
Industries & applications for DLC coatings
- Biocompatible coatings such as hip replacements and dental implants.
- Functional coatings (including DLC coatings) for friction-bearing surfaces such as high-performance engine parts and firearms.
- Durable-decorative coatings for plumbing products, sporting goods, jewelry & watches, and electronics.

Comparison to other coatings
Compared to powder coating, PVD coatings are more than 50 times thinner, last longer, and improve UV resistance vs. an organic polymer.
Compared to electroplating, PVD coatings have improved scratch and wear resistance, more color options, a cleaner, safer process, and offer the option of use after electroplating for wear-resistance and aesthetics.
Advantages of PVD coating
Some advantages of extremely-thin PVD finishing are:
- Coating complex geometries
- Improved appearance
- A vast array of colors
- Waste reduction
- A pennies-per-part coating cost
