pvd hARD COATING
PVD hard coating uses a similar vacuum deposition coating method as the standard PVD coating. Both multi arc and magnetron sputtering coating technologies can be used for the PVD hard coating.
- The differences between PVD hard coating and the standard PVD coating are:
The materials enclosed in the vacuum chamber are heated to a maximum temperature of 500 celcius
- The duration of the coating time is longer
- 10x hardness
PVD hard coating is one of the best methods for optimising the hardness to residual compressive stress ratio. The vacuum deposition method coats the product with
a film of hard refractory material 2-7 microns thick.
types of pvd hard coating
The types of PVD hard coating are Titanium Nitride (TiN), Titanium Carbide (TiC), Titanium Carbo-Nitride (TiCN), Aluminium Titanium Nitride (AlTiN) or Titanium Aluminium Nitride (TiAIN), Chromium Nitride (CrN), Aluminium Chromium Nitride (AlCrN) and Chromium Aluminium Titanium Nitride (CrAITiN) coating.
