Coatings

TiN

TiN is the most common coating. It has an hardness of 2200-2400 HV0.25, a friction factor of 0,4 and it maintains  its mechanical characteristics until  500-550°C. It is fit for the deep drilling, and the hobbing of low alloyed materials with low to mid cutting parameters with lubrification. It's widely used for the plastic moulding, cold forming and blanking of Fe or galvanised sheet.

TiCN

This coating is an evolution of the TiN in which some titanium carbon nitride layers have been added in order to make it harder and more resistant to wear. The hardness is 3000-3200 HV0.25, the friction factor is 0,3, and it maintains its mechanical characteristics until 400-450°C.
The better mechanical characteristics in comparison with TiN allow to mill alloyed steel with medium to high cutting parameters and with lubrification, but it is not suitable for the drilling because it is less resistant to the temperature. This coating can be used for the cold padding and the blanking of ferrous, non ferrous materials and inox.

TiAIN

This coating is the coating par excellence for deep drilling, hobbing, and milling with high cutting parameters of tough materials. The hardness is 3200-3500 HV0.25, the friction factor is 0,3, and it maintains its mechanical characteristics until 800-900°C.

CrN

The hardness of CrN is 2000-2200 HV0.25, the friction factor is 0,5, and it maintains its mechanical characteristics until 600-650°C. The more indicated applications for this coating are the plastic moulding, the aluminium extrusion and forming, and the aluminium die casting. At last, thanks to the high resistance to wear and corrosion, The CrN is fit for protecting mechanical sliding compounds.

Decorativo

The PVD technology is ecological and allows to deposit metallical coating with resistance to wear and corrosion properties definitively higher than the classical galvanised chromium plating.
The range of colours is from yellow-gold, copper to black, and is used to coat taps, handles, or jewellery.
It is possible to personalise the coating colour, on demand of the customer, also for small to mid production.
