AlTiN nano – Alluminum Titanium Nitride nanolayer coating



CHARACTERISTICS

Its formulation, is based on nanolayers of nitrides of titanium and aluminum, gives this coating characteristics of low friction coefficient and excellent toughness, combined with a high surface hardness.

The particular deposition technology (LARC ® - Lateral Rotating Arc Cathods) allows to obtain a coating almost free from droplets, the microdroplets characteristics of the electric arc technology, and then a particularly smooth surface. The very high percentage of aluminum, close to 70%, allows the formation of a layer of aluminum oxide (Al2O3), which creates a thermal barrier efficacies, up to temperatures of use next to 900° C.

We also realize the LT version (Low Temperature) with reduced deposition temperature, down to 300 ° C, for special applications.

Realizziamo anche la versione LT (Low Temperature) con temperatura di deposizione ridotta fino a 300°C, per applicazioni speciali.

 

APPLICATIONS

AlTiN nano is used on drills and mill cutters of steel and carbide, for general applications but also for high-speed machining of ferrous materials with hardness up to 55-56 HRC.

The characteristics of AlTiN nano make it suitable for applications in molds for shearing and shaping of ferrous materials.

One application that is particularly efficacies in molds and punches for the sintering of metal powders, where the high hardness and the almost total absence of droplets allow a better sliding of the powders and a consequent increase in the density of the sintered products.

The dark purple color of this coating also makes it suitable for decorative applications, where the characteristic resistance to scratching and matching to a particular substrate preparation in order to make IT reflective, make AlTiN nano coating particularly appreciated.
