How Does PVD Coating Work?
The solid metal is vaporized or ionized in a high vacuum
environment and deposited on electrically conductive materials as a
pure metal or metal alloy films. When a reactive gas, such as
nitrogen, oxygen or a hydrocarbon-based gas is introduced to the
metallic vapor, it creates nitride, oxide, or carbide coatings as
the metallic vapor stream, chemically reacts with the gasses. PVD
coating must be done in a specialized reaction chamber so that the
vaporized material doesn’t react with any contaminants that would
otherwise be present in the room.
During the process of PVD coating, the process parameters are
closely monitored and controlled so that the resulting film
hardness, adhesion, chemical resistance, film structure, and other
properties are repeatable for each run. Various PVD coating are
used to increase wear resistance, reduce friction, improve
appearance, and achieve other performance enhancements.
In order to deposit high purity materials such as titanium,
chromium, or zirconium, silver, gold, aluminum, copper, stainless
steel, the physical process of PVD coating utilizes one of several
different PVD coating methods, including:
Arc evaporation
Thermal evaporation
DC/MF sputtering(the bombardment of ions)
Ion Beam Deposition
Ion plating
Enhanced sputtering
Each of these methods belong in the overarching category of
“physical vapor deposition”.
EMI shielding vacuum coater:
1) Suitable for plastics,ceramics,glass and metal,surfaces
deposition,
2) Double-doors structuret,high productivity
3) High depositing speed, shorter time
4) Good uniformity & accurate coating thickness control
PVD EMI shileding Coating Benefits:
1) Process is environmentally friendly
2) Low investment and high payback for owner;
3) High volume production, fast cycle, low cost;
4) Unique design is friendly operation and low maintenance.
What is PVD coating?
PVD coating, or Physical Vapor Deposition coating, defines a
variety of vacuum coating methods. These coating techniques are
used to apply an extremely thin film to objects that require
protective barriers, decorative colors, or various other functional
benefits. It is a typeof vavuum deposition process where a material
is vaporized in a vacuum chamber, transported atom by atom across
the chamber to the substrate, and condensed into a film at the
substrate’s surface.
