What is PVD coating?
PVD coating stands for Physical Vapor Deposition coating, which is a thin film coating process used in many industries such as aerospace, automotive, medical, and more. It is a vacuum coating process that produces a hard, durable, and decorative finish on many different types of surfaces.
PVD coating is a multi-step process that involves the use of vacuum and thermal technology. The substrate is placed in a vacuum chamber, and a solid metal is heated until it vaporizes and covers the surface of the substrate in a thin layer. This process produces a high-quality finish that is resistant to wear, abrasion, and corrosion and provides a strong bond to the substrate.
- PVD coating is a popular alternative to other coating methods such as electroplating and painting.
- It is an eco-friendly process since it does not produce harmful byproducts, and the materials used are not hazardous to the environment or people.
- PVD coating can be applied to many different materials, including metals, plastics, ceramics, and glass.
How is PVD coating applied?
PVD coating, also known as Physical Vapor Deposition, is a surface coating technique that gives hard-wearing and corrosion-resistant layers to metals and other materials. This technique involves the deposition of a thin film onto a substrate using a vacuum chamber. Here are the steps involved in the process of PVD coating:
- Cleaning the Surface – The first step in PVD coating is to clean the surface of the substrate. This process is necessary to remove any dirt, oils, or other impurities that may interfere with the adhesion of the PVD coating. The surface of the substrate is usually grit-blasted or polished to ensure that it is smooth and free from contaminants.
- Preparation of the Chamber – After cleaning the substrate, it is placed inside a vacuum chamber. The chamber is then pumped down to a low pressure to remove all the air and impurities. The substrate is heated to a specific temperature inside the chamber to prepare it for coating.
- Introduction of the Coating Material – Once the substrate reaches the desired temperature, the coating material is fed into the vacuum chamber in a vapor form. The coating material can be in the form of a solid, liquid, or gas.
- Deposition of the Coating – The coating material is ionized inside the vacuum chamber, which causes it to condense onto the surface of the substrate. This process results in the formation of a thin film coating on the substrate. The thickness of the coating can be controlled by adjusting the parameters of the deposition process.
- Finishing – After deposition, the coated substrate is cooled down to room temperature before it is removed from the vacuum chamber. The resulting PVD-coated substrate is a hard-wearing surface with high corrosion resistance.
What materials can be PVD coated?
Physical Vapor Deposition (PVD) coating is a thin film deposition technique that is used to enhance or modify the surface properties of various materials. The PVD process can be applied to a wide range of materials, including:
- Metal alloys
- Plastics

- Brass
- Copper
The PVD coating process can be used on materials of different shapes and sizes, which makes it a versatile technology. It is used in numerous industries such as automotive, aerospace, medical, and military, where the coating is essential for improving the performance and appearance of the product.
PVD Coating Thickness Range
The thickness of the PVD coating depends on the material to be coated, the composition of the coating material, and the intended use of the product. In general, the PVD coating thickness ranges from 0.1 to 10 microns. A thicker coating provides more protection to the material and increases its wear resistance. The thickness of the PVD coating is measured by various analytical techniques, including x-ray diffraction, electron microscopy, and surface profilometry.
Can PVD Coating be Applied to Plastics?
PVD coating can be applied to a wide array of materials such as metals, ceramics, and even plastics. Plastic materials have been gaining attention in recent years due to their lightweight, flexibility, and customizable shape. However, coating plastics with PVD poses a unique challenge as plastics are vulnerable to high-temperature processing and may deform or melt during PVD coating.
- The plastic must be able to withstand the high temperature of the PVD coating process, usually around 450-500°C.
- The surface of the plastic must also be clean and free from any contaminants, including the molds used in the manufacturing process.
- The plastic must also have an appropriate surface texture to ensure the PVD coating adheres well, and there are various pretreatments available to achieve this, such as sandblasting or plasma treatment.
With careful consideration and preparation, PVD coating can be successfully applied to plastics. Some of the benefits of PVD coating on plastics include increased wear resistance, improved appearance, and corrosion protection.
However, the durability and longevity of the PVD coating on plastics may be affected by various factors such as the type of plastic, the environmental conditions it is exposed to, and the application of force or wear. A table showing the durability of PVD coating on different plastics can be seen below:
| Plastic Type | Expected Durability of PVD Coating |
|---|---|
| Acrylic | Low to Moderate |
| Polycarbonate | Low to Moderate |
| Polypropylene | Low |
| Polyethylene | Low |
| Polyethylene Terephthalate (PET) | Moderate to High |
It’s important to note that these are expected durabilities and actual results may vary depending on the application and environmental conditions. Consulting with a PVD coating specialist can help determine the best approach for applying PVD coating to plastics to ensure the best possible results.
