The pvd coating machine can coat a variety of colors, so how much do you know about the coating color of the coating machine?

The working principle of vacuum coating: Physical vapor deposition (Physical Vapor Deposition, PVD) technology means that under vacuum conditions, using physical methods, the material source-solid or liquid surface is vaporized into gaseous atoms, molecules or partially ionized into ions, and passed through. A low-pressure gas (or plasma) process, a technique for depositing a thin film with a special function on the surface of a substrate.

So how did his color come about? In a high vacuum and high temperature furnace, different gases are added, and the emitted ions can be combined to form different colors, and then the changed ions are deposited on the surface of the product to form a dense film. If N2 is added, the plated color will be gold; if C₂H₂ is added, the color will be black; if O2 is added, the color will be colorful and blue; if N2 and C₂H₂ are added, the color will be rose gold, etc., so the colors are various The effect of the intersection of gases and ions. You may wonder why some of the same gases have two different colors? The combination of gas and ions forms the entire color system, but the depth and change of the color are also affected by air pressure and time, which are usually proportional to the trend. As a special-shaped substance, thin films, like bulk substances, can be amorphous, polycrystalline and single-crystalline. It can be made of elemental elements or compounds, as well as inorganic materials or organic materials. Thin film process technologies include: physical vapor deposition (evaporation, sputtering, ion plating, arc plating, plasma plating) and chemical vapor deposition. The technology used in our factory production is Physical Vapor Deposition (PVD for short).
        The second is the type of polishing treatment. In the process of processing, transportation, storage, etc., the surface of hardware workpieces often has rust spots, macular, polishing wax, oil stains and other pollutants. In order to improve the beauty, applicability and corrosion resistance of the product, the The product must be subjected to pretreatment such as sanding, polishing or sandblasting, and then vacuum coating, and surface treatment is also a key step to improve the bonding force between metal and vacuum coating. Common polished surfaces are: laser light, mirror light, sanding and vibrating light.
        Does vacuum plating change the surface finish? In fact, for each different polishing effect, the unevenness on the surface of the product is inconsistent, and the reflection of light on the surface of the product is different, so the surface pretreatment of different products is different, the luminosity of refraction will be different, and the color is also different. different. Vacuum coating is the process of transferring atoms or molecules from the source to the surface of the substrate. It is a physical process of material transfer. PVD vacuum coating generally does not change or affect the surface luminosity of the product, so the bright color or surface effect is related to the product itself. big reason
        Frequently Asked Questions, why is the color of my product not as bright as other products after being coated by a pvd coating machine? First of all, for mirror light products with different finishes, even if they are produced in the same process, the effect after coating will still be different, so the brightness of the product is still closely related to the product itself. And the products from the same furnace have different colors? PVD vacuum coating is a physical combination between ions, not a fixed color added to the outside world, so even if it is a product made with the same parameters, the color will be inconsistent due to the material and surface treatment of the product.
