What are the Available Colors of PVD coating?
There are many different colors that can be achieved with PVD coatings, including metallic shades such as gold, rose gold, and bronze, as well as a wide range of non-metallic colors such as black, blue, green, and red. The exact color of the PVD coating depends on the material being vaporized and the conditions of the deposition process.
Below are the typical colors of the PVD coating:
- Rose gold
- Yellow gold
- Champagne Gold
- Mixed Multicolor
The choice of color for a particular product will depend on the desired aesthetic and the specific properties and functionality required for the product. Yellow gold and rose gold are popular colors for PVD-coated jewelry, as they can mimic the appearance of traditional gold without the high cost. Black and gold are also popular colors for PVD-coated watches, as they can give a sleek and sophisticated look.
In addition to the standard colors available, it is possible to create custom colors by combining different materials or altering the deposition conditions. PVD coatings can be applied to a wide range of materials, including metals, ceramics, glasses, and plastics, making them a versatile choice for a wide range of applications.
What Factors can Affect the Colors of PVD Coating?
There are several factors that can affect the color of Physical Vapor Deposition (PVD) coating:
Type of Material being Coated: The color of the PVD coating will depend on the type of material being coated. Different materials will absorb different wavelengths of light, resulting in different colors.
Type of PVD Process Used: Several types of PVD processes, such as sputtering and evaporation, can produce different colors.
Composition of the Coating: The color of the PVD coating can be affected by the composition of the coating material. Different elements and compounds can absorb different wavelengths of light, resulting in different colors.
The Thickness of the Coating: The color of the PVD coating can be affected by the thickness of the coating. Thicker coatings may appear darker, while thinner coatings may appear lighter.
Substrate Roughness: The substrate’s roughness can affect how light is reflected off the surface, which can affect the perceived color of the coating.
The Angle of Incidence: The angle at which light hits the coated surface can also affect the perceived color of the coating.
Post-processing Treatments: The color of the PVD coating can be modified through post-processing treatments, such as heat treatment or chemical treatment.
