Common industrial coatings applied by PVD include:

1. Titanium Nitride (TiN): This is one of the most common PVD coatings, known for its wear protection properties. It is widely used in cutting tools and machine parts to enhance their durability and resistance to wear.

2. Aluminides, MCrAlYs, Al2O3, ZrO2, ZrN, CrN, TiCN, TiAlN: These materials are often deposited as single or multi-layer coatings. They are used for various purposes such as corrosion resistance, wear resistance, and thermal stability. For example, Al2O3 and ZrO2 are used in high-temperature applications due to their excellent thermal stability and resistance to oxidation.

3. Diamond-like Coatings (DLCs): These coatings offer high hardness and low friction, making them suitable for applications requiring both wear resistance and reduced friction. They are commonly used in automotive engine parts and precision tools.

4. Corrosion Resistant Coatings: PVD coatings are used to protect gas turbine blades and other components exposed to harsh environments. These coatings enhance the lifespan of these components by preventing corrosion and oxidation.

5. Wear Prevention Coatings: These are crucial for machine and press tools, where the prevention of wear is essential to maintain precision and efficiency. PVD coatings like TiN and TiAlN are often used for this purpose.

6. Decorative Coatings: PVD coatings are also used for decorative purposes, especially on plastics and watch components. They can provide a range of colors and finishes, enhancing the aesthetic appeal of the products.

7. Medical Implants and Surgical Tools: PVD coatings are applied to medical implants and surgical tools to improve their biocompatibility and wear resistance. Titanium and other biocompatible materials are commonly used in these applications.

8. Optical Lenses: PVD coatings are used to create anti-reflective layers on optical lenses, improving their performance and clarity.

9. Electronics: PVD coatings are used in electronics for applications such as aluminum tracks and ceramic resistors in electronic circuitry. They are also used to deposit thin films of gold to replace traditional plating methods.

These coatings are chosen for their ability to enhance the properties of the underlying materials, providing benefits such as increased durability, improved resistance to wear and corrosion, and enhanced aesthetic qualities. The versatility and effectiveness of PVD coatings make them a preferred choice in various high-tech industries including automotive, aerospace, medical, and electronics.
