TiN – Titanium Nitride coating



CHARACTERISTICS

The TiN coating is the best known and most widely used among the PVD coatings; it manages to combine a good hardness value at an excellent toughness and adhesion to substrates.

The TiN is also characterized by a reduced coefficient of friction and a high chemical inertness towards the materials with which it is put in contact.

 

APPLICATIONS

Its properties, that remain stable up to the oxidation temperature, allow the TiN to be used with success in all the processes with chips removal as well as in the various operations of molding, shearing and sintering.

We realize different customizations of TiN coating, each optimized for specific applications.

Examples:

  • TiN for Gleason-type solid mill cutter of our production, where the performance is almost doubled compared to traditional TiN;
  • LT (Low Temperature) version with coating temperature reduced to 300 ° C for special applications;
  • The realization of a TiN with improved corrosion resistance, for parts subject to stay in oxidizing environments;
  • The realization of TiN particularly smooth for the application to sintering dentate punches.
