PVD coating offers a wide range of color options, including metallic shades like gold, rose gold, and bronze, as well as non-metallic colors such as black, blue, green, and red. The specific color achieved depends on the material being vaporized and the conditions of the deposition process.
5 Color Categories Explained
1. Metallic Colors
Metallic colors like gold, rose gold, bronze, silver, and yellow gold are commonly used, especially in jewelry and watches. They mimic traditional gold without the high cost.
2. Non-Metallic Colors
Non-metallic colors such as black, blue, purple, red, green, turquoise, graphite, and champagne gold are also available. They offer a diverse palette for various applications.
3. Custom Colors
It is possible to create custom colors by altering the deposition conditions or combining different materials. This enhances the versatility of PVD coatings.
4. Factors Affecting Color
Different materials absorb different wavelengths of light, affecting the final color of the coating. Processes like sputtering and evaporation can produce different colors due to variations in how materials are vaporized and deposited. The specific elements and compounds in the coating material can alter the color by absorbing different light wavelengths. Thicker coatings may appear darker, while thinner ones may appear lighter, influencing the final appearance of the color.
5. Conclusion
PVD coatings offer a broad spectrum of color options, from traditional metallic shades to vibrant non-metallic hues. The ability to customize colors and the durability of these coatings make PVD a versatile and valuable technology across various industries, including jewelry, watchmaking, and consumer products.
