PVD COATING

Physical vapour deposition, just PVD coating, as we usually call it, refers to
vacuum ion plating and vacuum sputter plating; Generally speaking, ncvm coating
refers to vacuum evaporation coating. The basic principle of PVD surface
treatment is to vaporize the coating material under vacuum, and then deposit it
evenly on the surface of the target part through electrons. The advantages of
PVD are: good adhesion of coating (good mechanical properties), strong winding
ability (adjustable target position and electroplating path), good coating
quality (dense, uniform, high strength and long service life), simplified
cleaning process (with cleaning function), and a wide range of plating
materials (metal and non-metal can be plated).

Does PVD Coating Wear Off?
The wear resistance of PVD coating system is different with different
electroplating materials. For example, the CRN coating on the surface of
bearings and cutting tools has strong wear resistance and is not easy to wear
off.

Is PVD Better Than Stainless Steel?
PVD Physical Vapour Deposition is a surface treatment process. PVD surface
treatment aims to improve or improve the performance and appearance of metal
surfaces, and cannot be compared with the performance of cheap CNC material.

Types Of PVD Coating

There are different types of PVD coatings that can be offered depending on the
application requirements. Titanium Nitride (TiN), Chromium Nitride (CrN),
Titanium Aluminum Nitride (TiAlN), Titanium Boron Nitride (TiBN) are some
examples of PVD coatings.

PVD Coating Advantages

Physical vapour deposition coatings offer the following benefits:

PVD surface treatment has high hardness (2400-4000 HV) (~ 80-90 HRc).

PVD physical vapour deposition is high abrasion resistance.

PVD metal coating is low friction coefficient (high surface lubricity)

Reduced tool heating due to low thermal conductivity of PVD physical vapor
deposition.

Physical vapor deposition coating is well resistance to chemical environments

PVD metal finish can increase surface quality of the machined parts

Preventing the processed parts from adhering to the tool-mold surface

No change in dimensions due to PVD coating thickness at micron level

Decrease in tool cost per piece due to increased tool physical life

Decreasing in workbench downtime periods since tool change frequency are
decreased

PVD surface treatment can obtain homogeneous coating thickness in each area

PVD Coating Technology

PVD coatings can be applied on components using different PVD technologies such
as arc evaporation, magnetron sputtering to name a few. HEF specializes in
plasma enhanced magnetron sputtering, CAM (coating assisted by microwaves) and
modified arc evaporation coating technologies. PVD coating technology is the
most important one of the methods in which hard ceramic coatings can be
successfully applied on mold and tool surfaces. This PVD technology is based on
the principle of ionic accumulation of materials under vacuum by being
evaporated and/or sputtered on the surface, to which the coating is to be
applied.

PVD Coating Applications

PVD coating can be found in a broad range of products. For example, PVD surface
treatment is frequently used in architecture. There is a wide range of PVD
coating applications, which is why it is commonly used in high-tech industries.
Some of the industries and applications in which we have applied PVD physical
vapor deposition coating include coating on composites for aerospace, titanium
on medical implants and surgical tools, gold thin film to replace plating for
electronics, non-metal, chemical resistant oxides for semiconductor parts and
hard ceramic coatings for industrial tools.
