The PVD process, with a layer thickness in between 0,2 µm and 2 µm, presents exceptional aesthetical features as well as it guarantees a very long life for the durability:
The PVD Coating Division is able to treat a wide range of materials:
All colors can be supplied with different surface characteristics:
QC lab every day certifies aesthetic and technical quality. Each costumer can ask for specific control and tests to characterize different coatings. Just for example:
(Color Meter DIN 6174, Surface Rugosity Meter as per BS ISO 4287)
(Spectrophotometer with X-ray ISO 3497)
(NSS test, AASS test, CASS Test, UNI ISO 9227)
(micro-scratch test ASTM C1624)
(nano indentation ISO 14577-1)
Coating for functional applications usually have a variable thickness from 1 to 6 microns and coating temperature which can reach up to 550°C.
Deposition are similar as the ones described in Decorative coating & treatment section. However the principal purpose of these coatings is to increase working performance and operative endurance of the coated units significantly. Technical coatings are used in various fields due to their extreme hardness, good adhesion to the substrate, corrosion resistance, low friction coefficient.
Typical coatings in this field are: TIN, AlTiN, AlCrN, TiAIN, TiCN, CrN, ZrN, DLC. This last coating family can be realized using PVD technology or PECVD. DLC presents extra characteristics for hardness and low friction coefficient . Diamond like carbon coating has been used for industrial purposes only recently and its full potentiality has still to be discovered.
