PVD, also known as physical vapor deposition (PVD), is one of the most advanced coating technologies.Compared with other traditional coating methods and wet chemical coating methods.PVD is a more precise and accurate coating technology.It is applicable to many metal materials, and stainless steel is indeed the most widely used one.How much do you know about PVD stainless steel?
What is PVD stainless steel?
PVD stainless steel means that different metals in the form of vapors are deposited on the surface of stainless steel.These PVD coating stainless steel provides wear resistance, corrosion protection, aesthetic PVD finish, durability, sustainability, improve cleanability, and help in fiction reduction.
PVD stainless steel, as the name implies, is physical vapor deposition using vapor-form metal deposited onto the stainless steel surface.This metal vapor formation does not require any chemical reaction, but is a physical method of vapor formation.Physical vapor formation in PVD is accomplished by physical means such as heating, induction heating, resistance heating, electron beam, laser, and plasma.PVD surface treatment is precise and accurate because it is an atom-by-atom, top-down coating method.The specific key details are as follows:
For the best PVD surface treatment effect, the surface should be free of contamination and completely clean for good adhesion and PVD coating.The surface should be roughened for better adhesion.PVD stainless steel sheets for coating should be polished and buffed before coating.
PVD vacuum plating coatings must be firmly bonded to the stainless steel substrate, maintaining its performance for a longer service life.PVD surface treatment with good adhesion can be enhanced due to ion bombardment during deposition and proper cleaning effects.
Due to the atom-by-atom deposition method, the PVD surface treatment is uniform over the entire stainless steel surface. It has good consistency with the finished product.
Vapors are the gaseous state of matter and they can move to every space available to them due to their Brownian motion.This Brownian motion of vapors enables them to evenly cover complex shapes, giving them a uniform and consistent PVD surface effect.
The life of a PVD coating on stainless steel depends on the type of coating composition, its compatibility with the substrate, adhesion to the substrate, and most importantly, the environment in which it is used. A harsh and abrasive environment will damage the coating earlier than a healthier environment.In addition to avoiding harsh environments, maintenance and cleaning also play a key role in the life of PVD coatings.
For typical daily wear, PVD coating on stainless steel can last between 1 to 3 years before showing signs of wear.With careful maintenance and infrequent exposure to harsh conditions, the coating may last upwards of 5 years.
PVD coating provides the following advantages to stainless steel：
a. Low fiction
b. Increased wear resistance
c. Provides corrosion resistance
d. Aesthetics
e. Durability
f. Customization properties.
However,PVD coating provides the following disadvantages to stainless steel：
a.Thickness limitation
b.Expensive
c.Complex technique
d.Adhesion challenges
e.Metal that cannot be vaporized cannot be coated
f.Base material compatibility issues
g.Color variations.
Stainless steel is best known for its corrosion protection due to the presence of chromium but for high-tech applications and high aesthetic look only stainless steel is not enough.So, we surface-engineered the surface of stainless steel with PVD coating to enhance its properties. PVD stainless steel opens a long range of applications for stainless steel by increasing its wear resistance, high thermal sustainability, durability, and corrosion protection.
PVD stainless steel is popular in various industries due to its superior durability, aesthetics, wear resistance and corrosion resistance, including:
Exterior and interior elements of buildings are made of PVD stainless steel.
Smartphones, mobile phone and laptop bodies, washing machine and refrigerator parts, and other electronic devices are made of PVD stainless steel.
The utensils and utensils used in the kitchen are made of PVD stainless steel, which makes them durable and authentic.
Medical equipment is made of PVD stainless steel for wear resistance, corrosion resistance and cleanability.
PVD stainless steel has a lighter coating weight and lower material utilization, but it is highly effective and strong, making it the best choice for such high-tech applications.
PVD stainless steel gives jewelry a luxurious aesthetic appearance.
In summary, PVD stainless steel, as one of the world's most advanced coating technologies, has revolutionized the field of stainless steel surface engineering and coating, thereby enhancing its surface properties and providing stainless steel surface engineering with the ability and opportunity to be used in different applications to meet its desired applications.
