- Physical vapor deposition (PVD) is a fascinating technology that allows manufacturers to apply ultra-thin coatings to products to enhance their properties. These coatings, sometimes just nanometers thick, can make products more durable, colorful, reflective, or have other desirable qualities.
You might be surprised to learn that many everyday items you use leverage PVD coatings Here are 10 common products that often have PVD thin-film coatings:
1. Faucets and Fixtures
That sleek, metallic finish on your kitchen or bathroom faucet is likely a PVD coating. PVD allows a vast range of colors and sheens to be applied to faucets and fixtures. The coating also makes them highly resistant to corrosion, tarnishing, scratching and wear.
2. Door Hardware
Similarly, door handles, locks, hinges and other hardware often use PVD coatings for both decorative and protective purposes. The coating gives them an attractive, durable finish that lasts for years.
3. Jewelry
Many “gold” and “silver” fashion jewelry pieces are actually made from less expensive base metals with a PVD coating that looks like the precious metal. PVD coatings allow a wider range of colors and finishes than is possible with solid gold or silver.
4. Watches
Watch cases, bands, and faces are often PVD coated for scratch resistance, corrosion resistance, and color. A PVD coating can give a watch a unique look while protecting it from wear.
5. Automotive Trim
Many of the metallic trim pieces on both the exterior and interior of cars use PVD coatings. The coating provides an attractive finish and protects the parts from weathering and corrosion. PVD is an environmentally friendly alternative to older chrome plating processes.
6. Tools
Drill bits, saw blades, and other tools often have PVD coatings to improve their hardness and wear resistance. A titanium nitride PVD coating, for example, can drastically extend the life and performance of a steel drill bit.
7. Medical Devices
PVD is used to apply biocompatible coatings to medical implants, instruments, and other devices. These coatings can reduce friction, improve wear resistance, and prevent the growth of bacteria.
8. Aerospace Components
Critical aerospace parts like turbine blades and bearings use PVD coatings to withstand extreme temperatures, reduce friction, and resist corrosion. These coatings help improve aircraft efficiency and safety.
9. Semiconductors
PVD is a key process used in semiconductor and microelectronics manufacturing. It is used to deposit thin films of conductors, insulators, and other materials with precise control to make integrated circuits and other electronic components that power our digital world.
10. Architectural Glass
Energy-efficient windows often have a PVD coating that reflects infrared light to keep buildings cooler in the summer, while still allowing visible light to pass through. Other PVD coatings make glass more durable or easier to clean.
| Product Category | Common PVD Coatings Used | Key Benefits |
| Faucets & Fixtures | Zirconium Nitride, Chromium Nitride | Durability, Color, Corrosion Resistance |
| Jewelry | Titanium Nitride, Zirconium Nitride | Color, Wear Resistance |
| Tools | Titanium Nitride, Titanium Aluminum Nitride | Hardness, Wear Resistance |
| Semiconductors | Tantalum, Copper, Tungsten | Conductivity, Insulation, Diffusion Barriers |
As you can see, PVD coatings are all around us, improving the products we use every day. Advances in PVD technology, like the Co-Evaporation of Materials in PVD, are enabling even more sophisticated multi-layered and composite coatings.
As remarkable as PVD is today, its potential is just beginning to be realized.The next time you turn on a faucet, check the time, or use your computer, remember the unsung hero behind those experiences – the humble yet amazing PVD coating.
These microscopic marvels are working tirelessly to make our world a little bit better, one product at a time.
