BALIFOR TThe ta-C solution for high temperature environments in the automotive industry

Piston Pins

In some applications, BALINIT® DLC (Diamond-like-Carbon) coatings may reach their limits with respect to their operating temperatures exceeding more than 350° C, intermittently dry running and due to their incompatibility to aggressive additives (e.g. high concentration-MoDTC). Where BALINIT® DLC cannot meet the requirements, the ta-C-coating from Oerlikon Balzers, BALIFOR™ T, is the solution.

  • Advantages


    Setting the standards in coating technology for decades, Oerlikon Balzers has delivered ta-C coatings with a high energy arc-evaporation process for years, now rolling them out into the automotive market in one combined solution that includes pre- and post-treatment. This „package“ includes the unique Controlled Contact Pressure Post-Treatment Process explicitly customised by Oerlikon Balzers, thus constantly delivering reliable results.

    BALIFOR™ T offers the differentiating characteristics for:

    • High temperature applications (depending on pressure)
    • Low lubrication applications for longer periods
    • Aggressive additive environments
  • Specifications


    Coating material ta-C
    Coating structure Arc
    Coating colour black
    Coating hardness HIT[GPa]* > 40
    Coefficient of friction (dry) vs. steel** 0.1 - 0.2
    Max. service temp. [°C]**** 450
    Typical coating thickness [µm] 1 - 2
    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.
    **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.
    ****Max. service temp. [°C] These are approximate values out of the field. Due to thermodynamic laws there is a dependency of pressure in application.
