PVD (Physical Vapor Deposition) coatings are extremely durable and highly resistant to scratches.
While it is very difficult to scratch PVD coatings due to their hardness, which is almost comparable to diamonds, they can be removed by specialized services if desired.
4 Key Facts About PVD Coating Durability and Scratch Resistance
1. Exceptional Durability and Scratch Resistance
PVD coatings are known for their exceptional durability and resistance to scratches.
This is because the coating material is deposited at a molecular level, allowing for precise control over the film's density, structure, and stoichiometry.
This results in a coating that is very hard and resistant to wear and tear.
The surface hardness of PVD coatings can exceed that of the hardest steels, making them highly resistant to scratches.
2. Removal of PVD Coatings
Although PVD coatings are designed to be permanent and extremely difficult to remove, some manufacturers offer services to remove these coatings if a change is desired.
This process likely involves specialized techniques and equipment to safely and effectively strip the PVD coating from the surface.
3. Methods of PVD Coating
There are two primary methods used for PVD coating in jewelry: sputtering and cathodic-arc.
Sputtering is more commonly used as it operates at temperatures suitable for a wide range of materials.
In contrast, the cathodic-arc method, which involves extremely high temperatures, is less commonly used due to its potential to damage materials.
4. Additional Benefits
PVD coatings not only resist scratches but also provide resistance to corrosion, UV light, and saltwater, making them suitable for various environments including marine settings.
They also offer a range of aesthetic benefits, such as the ability to adjust the product's appearance through various uniform coating colors.
In conclusion, while PVD coatings are highly resistant to scratches and designed to be permanent, they can be removed through specialized services if necessary.
Their exceptional durability and resistance to various forms of damage make them a superior choice for many applications.
