PVD coatings are indeed shiny and have a metallic finish, which is a characteristic feature of products coated with this technique. The shine and metallic appearance are due to the deposition of thin layers of metal or ceramic materials in a high vacuum environment, which results in a high-quality, durable surface finish.
The process of PVD involves converting metal into a vaporous state and adding a reaction gas to create the coating. This method allows for a wide range of colors and finishes, making PVD coatings versatile for decorative applications such as watches, sanitary and door hardware. The coatings are not only visually appealing but also offer superior resistance to wear, tear, tarnishing, discoloration, and corrosion. They maintain their appearance over time, even under UV radiation, which is a significant advantage over traditional electroplated coatings.
Moreover, PVD coatings can be combined with various surface finishes like satin, mirror, and bead blasted, enhancing the aesthetic appeal and functionality of the products. The adhesion of PVD coatings to the substrate is very good, ensuring that the coated product retains its original shape and dimensional accuracy. Despite being extremely thin, typically ranging from 0.25 to 4.0 microns, these coatings provide excellent hardness, abrasion resistance, and temperature resistance, eliminating the need for additional top coatings or supports.
In summary, PVD coatings are indeed shiny and metallic, offering a high-quality, durable finish that is resistant to various forms of degradation. This makes them ideal for applications where both appearance and longevity are critical.
