As a professional PVD coating stainless steel supplier, we offer PVD-coated stainless steel for customers to choose from.
Our PVD coating stainless steel, with physical Vapor Deposition (PVD), is a process to produce a metal vapor (titanium, chromium, and aluminum) that can be deposited on electrically conductive materials as a thin highly adhered pure metal or alloy coating. The process is carried out in a vacuum chamber using a cathodic arc source.
Want more information on PVD Coated Stainless Steel? Feel free to contact us.
The coating compounds are made up of various elements such as carbides, nitrides, borides, and silicide. A wide variety of colors can be achieved by adding different gases during the deposition.
WHY CHOOSE PVD COATING?
- PVD coating is one of the best methods for enhancing thin film plating elements. The vacuum deposition method coats the product with a film of 0.1-0.3 microns thick.
- PVD coatings surpass traditional electroplated coatings, it's more corrosion resistant and has superior hardness.
- PVD coatings do not discolor or tarnish and do not suffer under UV radiation so easily.
- More environmentally friendly than traditional coating processes such as electroplating or painting.
WHY CHOOSE STANCH PVD COATING?
Our PVD coated stainless steel use Stanch innovative new techniques to make the PVD-colored coats much harder and more durable than others. The general coating deposition method coats the product with a film of 0.1-0.2 microns thick, but we make it thicker for better wear, scratch, and corrosion resistance making its durability superior to general coating methods such as electroplating or other PVD processes. Stanch new PVD technique can be achieved a smooth PVD coat with good scratch resistance compared to other PVD processes as well.

Applying PVD coatings to various products can add value by improving their appearance, performance, or both. The driving force for using PVD coatings is technical and/or economic limitations to manufacturing components entirely of a single material with all desired characteristics. That being the case, product design, including material selection, requires considering: application, the environment where the product will be used, cost of raw materials, manufacturing costs, final price to the customer, etc.
PVD coatings allow you to use base materials (aka ' substrate) that address most of the product's engineering needs and cost constraints by adding a protective, cosmetically appealing layer to the final manufactured part or tool.

Manufacturers often ask us about PVD coating durability. Some of the most common questions are:
- How long does a PVD coating last?
- Does a PVD coating wear off?
- What is a typical PVD coating thickness?
- What if the PVD-coated product is exposed to harsh 'chemical' environments?
- How durable is a PVD coating?
How long does a PVD coating last?
The ability of a PVD coating to remain functional and retain its cosmetic appearance depends on several factors:

- Coating material
- Coating thickness
- Adhesion between coating and substrate
- Type and hardness of the substrate
- Environment
- Application
Zirconium, titanium, and chromium are the base materials of choice for most decorative and performance coatings. When combined with nitrogen, carbon, and/or oxygen in the PVD process, these materials can produce a wide range of colors and achieve very high hardness, protecting against wear with an excellent cosmetic appearance.

PVD coating thickness
For comparison, high-quality tool steel used in drill bits has a hardness of around Vickers; the hardness of zirconium nitride (ZrN), for example, is typically about - Vickers.
Therefore, in decorative applications with mild to moderate wear, coatings a few tenths of micrometer (0.2 to 0.5μm) thick can withstand many years of use without significant wear.
For products that endure harsher wear conditions, not only does the selection of the coating material and thickness (typically >1μm) need to be considered, but the substrate should be harder to provide support to the coating. That is the case because, as it is very thin, the coating can deflect to the fracture point if the substrate yields under localized pressure in a stress situation. If using a product may expose it to gouging, for example, harder substrates and thicker PVD coatings are recommended.
How about PVD coating durability with exposure to harsh 'chemical' environments? Does the PVD coating wear off?
Another aspect of durability is the resistance to environmental conditions such as corrosion and oxidation, i.e., chemical stability. Carbides, nitrides, and oxides of metals are generally more chemically inert than their pure metallic forms. This characteristic means that PVD coatings can provide years of tarnish-free appearance to consumer products such as faucets, door hardware, smart phones, etc. In the case of coatings used in tools, e.g., for machining, injection molding, punching applications, etc., wear resistance, and chemical stability are required. Choosing the correct coating can increase tool life and productivity by orders of magnitude.
In summary:
- Durable PVD coatings add long-lasting protection while maintaining the product's cosmetic appearance.
- The careful design of a product should include a proper selection of the core material and the type and thickness of the PVD coating.
- PVD coatings extend tool life (which may mean less maintenance and tool changes and reduced scrap). Actual cost savings due to improved durability will depend on the application and type of coating.
