BALINIT A Titanium nitride from the start – The world’s first wear protective PVD coating

Thread Former Coated
Food-safe and often used for medical instruments
Gold Coating

It all began with titanium nitride. BALINIT® A moreover continues to be a versatile wear protection coating that provides effective reduction of abrasive and adhesive wear in many varied applications.

It is also applied decoratively or as a wear indicator, or used for special applications as low-temperature coating BALINIT® A ARCTIC at temperatures up to 200 °C.

Initial trials of TiN-coated forming tools in 1977 were very successful: service life was increased by a factor of 4. Development and marketing of PVD hard coatings for tools was given the official go-ahead one year later on 1 September  1978. 

  • Balzers’s first wear protective PVD coating
  • Available as a low-temperature coating
  • Versatility since 1978
  • Food-safe
  • Decorative gold-yellow color
Coating material TiN
Coating technology Arc
Coating colour gold-yellow
Coating hardness HIT [GPa]* 30 +/- 3
Coefficient of friction (dry) vs. steel** ~0.6
Intrinsic stress [GPa]*** -2 +/-1
Max. service temp. [°C]**** 600
Process temperature [°C] < 500
General remark All given data are approximate values, they depend on application, environment and test condition.
*Coating hardness HIT [GPa] Measured by nano indentation according to ISO 14577. For multilayers the hardness of the different layers varies. Hardness can be adapted to the application.
**Coefficient of friction (dry) vs. steel Determined by ball-on-disc test in dry condition with an Steel ball according to ASTM G99. During run-in the given values may be exceeded.
***Intrinsic stress [GPa] Measured by XRD and/or bending method (Stoney equation). The calculated thermal stress has been substracted.
****Max. service temp. [°C] These are approximate values out of the field. Due to thermodynamic laws there is a dependency of pressure in application.
