Product Description

PVD (Physical Vapor Deposition) decorative coatings are thin films deposited onto surfaces to enhance their appearance and provide various functional properties. One popular type of PVD coating known for its rainbow colors is called "PVD rainbow color coating" or "PVD rainbow coating."


PVD rainbow color coating involves the deposition of multiple thin layers of different materials onto a substrate using the PVD process. Each layer has a specific thickness, composition, and refractive index, which interact with light in a way that produces a colorful, iridescent effect. The resulting colors can resemble a rainbow or exhibit a vibrant, metallic sheen.


The exact composition and layering sequence of the PVD rainbow color coating can vary depending on the desired effect and the manufacturer's proprietary techniques. However, commonly used materials in these coatings include metal nitrides, oxides, and carbides.


The rainbow effect in PVD coatings is primarily attributed to thin-film interference and the phenomenon of constructive and destructive interference of light waves. When light interacts with the multiple layers of the coating, some wavelengths are reflected while others interfere constructively or destructively, resulting in a spectral play of colors.


The appearance of the rainbow colors can change depending on the viewing angle, lighting conditions, and the thickness and composition of the coating layers. This dynamic and visually appealing effect has made PVD rainbow coatings popular for decorative applications in industries such as jewelry, watches, automotive accessories, and architectural accents.


It's important to note that PVD rainbow coatings are typically applied in a controlled vacuum environment using specialized equipment. The process involves physical vaporization of the coating material, which then condenses onto the substrate to form the thin film.


Overall, PVD rainbow color coatings are a visually stunning option for achieving vibrant and iridescent finishes on various surfaces, adding an aesthetic appeal to a wide range of products and applications.

PVD Techniques for Rainbow Color Generation. 


Normally, we generate the PVD rainbow colors by  cathodic arc or magnetron sputtering techniques through 

Titanium targets and Oxygen gas. The film is TiO. 



Arc Plating: Arc plating, also known as cathodic arc deposition, involves the use of an electric arc to vaporize the coating material. In this process, a high-current arc is struck between a cathode target (consisting of the coating material) and an anode. The arc vaporizes the target material, creating a plasma plume. The plasma plume is then directed towards the substrate, where it condenses and forms a coating.


To achieve rainbow colors using arc plating, multiple cathodes made of different materials or compositions are used. Each cathode is responsible for depositing a specific layer in the coating stack. By sequentially activating and deactivating the cathodes during the deposition process, different layers with varying properties and thicknesses are deposited, leading to the rainbow effect. The specific layering sequence and deposition parameters are carefully controlled to produce the desired color palette and visual appearance.


Sputtering: Sputtering is another widely used technique in PVD processes. It involves bombarding a target material with high-energy ions in a low-pressure gas environment. The ion bombardment dislodges atoms from the target, which then travel in a straight line and deposit onto the substrate.

To create rainbow coatings using sputtering, a similar approach to arc plating can be employed. Multiple targets made of different materials or compositions are used, and each target is responsible for depositing a specific layer in the coating stack. By sequentially sputtering the different targets, the various layers are built up, resulting in the rainbow effect. The control of the sputtering process parameters, such as power, pressure, and gas composition, is crucial for achieving the desired coloration and visual effects.


In both arc plating and sputtering, the precise control of deposition parameters, such as layer thickness, composition, and sequence, is essential to produce the desired rainbow colors. The exact layering scheme and materials used may vary between manufacturers, as proprietary techniques and formulations are often developed to achieve specific visual effects.


It's important to note that both arc plating and sputtering methods require specialized equipment and expertise to carry out the deposition process under controlled conditions. These techniques are widely used in industries such as decorative coatings, jewelry, automotive accessories, and architectural applications to achieve visually appealing and vibrant rainbow finishes.


PVD rainbow coating applications:


PVD rainbow coatings find applications in various industries where a visually striking and colorful appearance is desired. Some common applications include:


Jewelry: PVD rainbow coatings are popular in the jewelry industry. They are used to enhance the aesthetic appeal of rings, earrings, necklaces, and bracelets, providing a vibrant and iridescent finish. Rainbow coatings can add a unique and eye-catching element to precious metals and gemstones.


Watches: Many watch manufacturers utilize PVD rainbow coatings to create captivating and luxurious timepiece designs. The rainbow effect adds a dynamic and sophisticated look to watch cases, dials, and straps, making them stand out as fashion accessories.


Automotive Accessories: PVD rainbow coatings are applied to automotive accessories such as trim pieces, emblems, and wheels. These coatings add a touch of color and shine to the vehicle's exterior, allowing for customization and personalization options.


Architectural Accents: In architectural design, PVD rainbow coatings can be used on various metal surfaces, including door handles, handrails, and decorative fixtures. They provide a visually appealing and modern aesthetic, giving architectural elements a unique and vibrant appearance.


Consumer Electronics: PVD rainbow coatings are employed in the consumer electronics industry to enhance the visual appeal of devices such as smartphones, tablets, and laptops. The coatings can be applied to metallic components, giving them a colorful and eye-catching finish.


Fashion Accessories: Rainbow coatings are also utilized in fashion accessories like belt buckles, handbag hardware, and eyewear frames. These coatings add a touch of elegance and uniqueness to the accessories, making them stand out in the fashion industry.


Cosmetics Packaging: PVD rainbow coatings are sometimes used in the packaging of cosmetics, such as perfume bottles and cosmetic containers. The coatings provide a high-end and visually pleasing appearance, contributing to the overall branding and consumer experience.


It's worth noting that the applications of PVD rainbow coatings are not limited to the examples mentioned above. The versatility and visually appealing nature of these coatings make them suitable for various other industries and products where a stunning and colorful finish is desired.
