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:
