As you may already know, aesthetic value accounts for up to 50% of customers’ product selection criteria. Therefore, many businesses today place greater emphasis on improving the aesthetic value of their products through various methods. One of the widely used methods in recent times is PVD coating technology. This technology has had a significant impact on the economic value of products as it can simultaneously achieve two tasks: enhancing aesthetics and providing excellent product protection. In this article, PAVICO provides an overview of PVD coating technology.
What is PVD Coating?
PVD coating technology, also known as physical vapor deposition (PVD), allows the creation of a durable metal coating on the surface of a material substrate. To perform PVD coating, the coating material is introduced into a vacuum chamber and transformed from a solid to a vapor state. Subsequently, it returns to the solid state as a thin film condensed on the surface of the substrate.
The Operating Principle of PVD Coating
PVD coating technology operates based on the principles of thermal dynamics. In this process, energy is primarily focused on the solid precursor material. To break the bonds of the solid precursor material, three different methods can be used: sputtering, arc evaporation, and laser ablation. In doing so, the generated energy disrupts the crystal structure of the material. At the same time, atoms become ionized and are released from the solid precursor material. They then move to the substrate and deposit as a thin film using the gradient pressure method. Some essential parameters of PVD coating technology that you should be aware of are:
Hardness: 1000 to 4000 HV
Temperature resistance: 300 to 1150°C
Deposition temperature: 200 to 600°C
Coating thickness: 0.5 to 10
Coating structure: Nano Composite Layer/Single Layer/Superfine Alloy Layer/Gradient Layer/Multi-Layer
The Vacuum PVD Coating Process
The PVD coating process goes through four stages: vaporization of the metal, transportation, reaction, and deposition. In the vaporization stage, the coating material is introduced into a vacuum chamber and vaporized. During this process, metal ions are formed. Next, the ions move to the coating material under the influence of a magnetic field, which is known as transportation.
After transportation comes the reaction stage. In this stage, gas ions combine with the metal ions at the electrode to create a colored mixture. Different colors have different ratios, providing a wide range of color tones. You can choose the one that best suits your product. Finally, we reach the deposition stage, where the coating layer is formed on the material.
Advantages of PVD Coating
Currently, the use of PVD coating has become a trend among businesses because they recognize its numerous benefits. Besides enhancing aesthetic value, PVD coating effectively protects the product’s surface. Here are some advantages of PVD coating technology:
- Exceptional improvement in aesthetic value
- Effective protection of the product’s surface from environmental chemical factors
- Mitigation of corrosion, extending product lifespan
- Outstanding adhesion of the PVD layer
- Environmentally safe and friendly.

Applications of PVD Coating
Technology PVD coating technology is widely applied in various fields today. It can effectively coat a variety of materials, including plastics, metals, stainless steel, and more. With its excellent surface protection capabilities, this coating technology enhances the economic value of businesses effectively.
One of the fantastic applications of PVD coating is in the fashion and feng shui industries. This includes items such as statues, watches, bracelets, and more. Manufacturers can create custom colors for their products using PVD coating, thanks to its rich and diverse color palette. Different mixing ratios result in various color tones.
Moreover, PVD coating finds excellent use in the household goods sector. Products like faucets and showerheads benefit greatly from this technology. By using PVD coating, your household appliances are maximally protected from environmental factors. Additionally, it minimizes scratches and corrosion, extending the lifespan of the products.
Furthermore, PVD coating is now being applied in other fields like healthcare and construction. With its outstanding advantages, it deserves to be considered the best coating technology available today. You can have complete confidence in the quality and durability of products coated with vacuum PVD technology.
