Technical features of the coating
| Coating colour | Hardness | Elastic modulus E | Oxidation temp. | Coeff. of friction on 100Cr6 | Deposition temp. | Typical thickness |
|---|---|---|---|---|---|---|
| Dark purple | 3200 ± 60 HV | 340 ± 10 GPa | 900°C | 0,40 | 300°C | 1-4 μm |
Its formulation, based on titanium and aluminium nanolayers, provides this coating with properties such as a low coefficient of friction and an excellent toughness, in addition to a high superficial hardness.
Its special deposition technology (LARC® – Lateral Rotating Arc Cathods) allows to obtain a coating which is almost free from the typical microdroplets produced by the electric arc technology, resulting therefore in a particularly smooth surface.
Its very high percentage of aluminium, close to 70%, allows the formation of a layer of aluminium oxide (Al2O3) which creates a thermal barrier effective up to working temperatures that are close to 900 °C.
We also produce the LT (Low Temperature) version whose deposition temperature is reduced to 300 °C for special applications.
AlTiN Nano is used on steel and carbide drills and milling cutters, for general applications but also for the high-speed machining of ferrous materials with a hardness up to 50 HRC.
SHEARING AND BENDING DIESWith its properties, AlTiN Nano is also suitable for application on dies for the shearing and the forming of ferrous metals.
SINTERING MOULDSA particularly effective application is on moulds and punches for the sintering of metal powders, where its high hardness and the almost complete absence of droplets allow a better flow of the powders and a subsequent increase in the density of the sintered products.
DECORATIVE APPLICATIONSThe dark purple colour of this coating makes it also suitable for decorative applications, where its distinctive resistance to scratching, coupled with a particular preparation of the substrate to make it anti-reflective, make AlTiN Nano a particularly appreciated coating.
Suitable for application on mechanical tools in general, hot deformation and shearing dies, and especially metal sintering moulds.
