Gold PVD coatings are known for their exceptional durability and hardness.
These coatings do not typically come off on their own due to their robust nature.
However, if removal is desired, specific de-coating processes are available.
These processes ensure that the underlying substrate remains unharmed.
1. Durability of Gold PVD Coatings
Gold PVD coatings are almost as hard as diamonds.
This hardness makes them highly resistant to scratches and wear.
The coating process ensures close adherence to the surface, enhancing durability.
2. Removal of Gold PVD Coatings
If a change in appearance or color is needed, gold PVD coatings can be removed.
Many manufacturers offer specialized de-coating services.
These processes remove only the coating layers, preserving the substrate's integrity.
3. Application and Longevity of Gold PVD Coatings
Gold PVD coatings are widely used in industries like jewelry and watchmaking.
They maintain a lustrous appearance without tarnishing.
Properly applied and maintained, these coatings can last up to 10 years.
4. Techniques Used in Gold PVD Coating
Two primary methods are used: Sputtering PVD and Cathodic-Arc PVD.
Sputtering is more common due to its suitability for a wide range of materials.
Cathodic-Arc PVD, though less frequently used, involves extremely high temperatures.
