There is a popular coating on stainless steel called PVD, which is used to manufacture many furniture and other home decor items. This finish is not only beautiful but also enduring.
PVD coatings are a thin yet highly durable coating placed on many different substrates, including stainless steel. A vacuum chamber with very high temperatures is used to apply the PVD coating. Though this finish is used a lot in the tech, medical and aerospace industries, it is also used for home decor and home furniture products.
What is the PVD Stainless Steel Coating?
PVD coatings are thin-film coatings where a solid material is placed on another material to produce a lasting coat. In our case, we place the PVD coating on stainless steel. The thin coatings are between 0.5 microns to 5 microns, depending on the color and required process.
PVD stands for Physical Vapor Deposition. Basically, what this means in layman’s terms is that a skinny coat of a metal vapor is placed on the surface of an object through a vacuum chamber and very high temperatures.
This is the basic process of producing a PVD stainless steel finish:
- Vacuum Chamber – The solid material is vaporized in a vacuum chamber.
- High Temperature – In the vacuum chamber, the temperature is between 122 to 1,112-degree Fahrenheit (50 to 600 degrees Celsius). So it is fired at extremely high temperatures.
- Deposit on Material – In the vacuum chamber, the PVD gets deposited or placed on the material.
- Needs to Rotate – Usually, while applying a PVD coating, the object needs to be rotated to ensure the heat and the application are even. The chamber position and rotating is an essential part of the PVD coating.
- Coating Properties- When the PVD coating is placed on the metal’s surface, it then changes the properties of the metal itself.
- Very Thin Coatings – The PVD is a very thin coating, usually between 0.5 microns to 5 microns depending on the color and the process required.
Some people may think this is the same thing as powder coating or painting the metal, but in reality, it is very different to manufacture a PVD coating; you must have the right equipment and a large enough vacuum chamber even to do this kind of coating. You cannot get the same properties, look or finish with any other process.
What Are PVD Applications or Uses?
Actually, PVD has a wide range of uses, and the coating can be placed on a wide range of materials and substrates. In the home decor and home furnishing industry, the PVD finish is placed mainly on stainless steel, but it is interesting to know about the other ways it can and is being used.
- PVD Coating Metals – The PVD coating uses titanium, zirconium, aluminum, stainless steel, copper, and gold. The gold coating is usually for the aerospace industry.
- Substrates with PVD coating – The substrates for the PVD application can be applied to ceramics, nylon, plastics, glass, and metals like stainless steel and aluminum.
- Industries that use PVD – Besides the furniture and home decor industry, PVD is used in many other industries. PVD coatings are commonly found in the high-tech industry. They are also used for aerospace, and titanium medical implants, and surgical tools. The PVD gold film is used a lot in the electronics industry. PVD coating is also used a lot in the semiconductor parts and industrial tools industry. It is also used on items like a golf club or watch hardware. Yes, your Apple Space Grey Watch and many of your Apple Phones have PVD coatings on them.
As you can see, actually, many other industries use PVD coatings much more than the home decor or home furniture industry. There are several reasons for this:
- PVD properties – The PVD finish is tough, giving a very hard and tough surface. Also, it has a low coefficient of friction, anti-corrosion, and wear resistance. These are all essential qualities, especially for the high tech or medical industry. Those are all qualities that you want to have if, for example, you have a plate put in your ankle as I had from a motorbike accident.
- Thin Coatings – As the PVD coatings are extremely thin, i.e., 0.5 microns to 5 microns, when they are coating precision tools, it will not throw the specification off for the precision tool or part.
- Extremely Durable – Even though the PVD coat is extremely thin, being only a .5 or a few microns, once the coating is applied, it is nearly impossible to remove and wear off on its own. This is one reason the PVD coating is so popular and has so many applications and uses.
What are the uses of PVD Finishes in the Home Decor and Home Furnishing Industry?
In the home decor and home furnishing industry, PVD is usually placed on stainless steel. Placing PVD on stainless steel gives a variety of interesting colors, looks, and finishes.
The PVD finish is quite technical and complicated to produce and requires very good equipment and skills by the factory making the PVD coating. So the PVD finish is usually more costly than using a finish like a gold leaf finish on metal or a basic powder coat. But we have found it is usually cheaper than solid brass. But the actual cost would need to be confirmed for each product and each use as there are a lot of variables as to the pricing on the PVD finish and other types of metal.
One of the great things about the PVD finish is that this is one of the toughest and most durable finishes out in the market today. This makes it an extremely important finish for the home decor and home furniture business.
Here are some of the basic uses for a PVD finish in the home decor and home furniture industry:
- Table Bases – One of the most common ways that PVD is used is for table bases. This is because the base is strong so even heavy materials as a large marble piece can be placed on top of the PVD base. The durability of the PVD finish is also one reason that the PVD finish is also used a lot in the hotel contracting Industry.
- Chair bases – A PVD metal base can be used as a chair base. Everything from smaller chairs to larger chairs or even a sofa frame. The ability to do the larger frames will, of course, depends on the size of the vacuum chamber that the supplier has as the PVD suppler will be limited by the size of the vacuum chamber.
- MIrror Frames and Wall Art – The PVD finish could be made into a mirror frame or a wall art piece.
- Hardware and parts – We have used PVD finishes for hardware and parts for other items such as boxes, trays, lamps, mirrors, wall art. Just about anything where you need or want to have a PVD part on. This is perhaps one of the best ways to use PVD finishes, in that you use the PVD finish as part of a design in home decor or home furniture item.
We love the PVD finish as it has not only a great look but is also extremely durable. We feel like it is an amazing finish that can be used in various home decor and home furniture products.
Is the PVD Coating Safe?
The PVD coating is safe. In fact, the food safeness of the PVD coating is inert. Also, the surface is extremely tough and durable, so the PVD coating should not chip, crack, or break. This also makes the PVD coating an extremely safe and tough coating for many uses. The fact this is used so much in the high tech, medical, and aerospace industry also testifies how safe and durable the PVD coating is.
How Do You Clean a PVD Coating?
To clean your PVD products, you need to use a soft cloth with mild soap and water. You should avoid all cleaning products designed to remove any rust or tarnish as these could damage or change the PVD coating.
Do not use any of these substances in any cleaning agents or products on a PVD coating:
- phosphoric acid
- caustic agents
