The titanium nitride layer has for a long time been the well-proven standard layer type through its balanced properties.
The golden titanium nitride layer, abbrev. TiN, indicates the following properties:
|Material:||Titanium nitride, TiN|
|Micro-hardness HV 0.05:||2300 ± 300|
|Coefficient of friction against steel 100Cr6:||0.6|
|Layer thickness [µm]:||2-4 |
|Maximums application temperature:||500° C / 900° F|
|General characteristic:||All-round coating|
|Preferred applications:||Processing / machining of iron based materials; metal shaping; plastic shaping|
 Dependent on tool size, for micro-tools also of less than 2 µm.
