BALINIT DLCExtremely hard and wear-resistant diamond-like carbon coatings


Diamond-like carbon (DLC) coatings are perfectly suited to the most extreme wear conditions and high sliding speeds, even without lubrication. They minimise frictional losses, making them ideal for engine components such as fuel injection systems, valve trains and pistons. Many other applications, ranging from pumps and compressors to bearing shells and rollers, and from textile machines to medical technology, also exploit the outstanding gliding properties of DLC coatings.

Through its extreme hardness, BALINIT® DLC provides excellent protection against abrasion, tribo-oxidation and adhesive wear, whilst permitting high surface pressures that would otherwise quickly cause scuffing and cold welding.

    *Hardness can be adapted to the application.

    Coating material a-C:H
    Coating structure PACVD
    Coating colour black
    Coating hardness HIT[GPa]* ~15-25
    Coefficient of friction (dry) vs. steel** 0.1 - 0.2
    Max. service temp. [°C]**** 300
    Coating temperature [°C] < 250
    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.
