Tribobond™ 49 DLC

Tribobond™ 49, the next generation of diamond-like carbon coatings

Tribobond 49 ta-C is a hydrogen and droplet-free DLC coating with an increased temperature resistance of up to 400°C compared to 250°C for hydrogenated DLC coatings. Tribobond 49 has an improved wear resistance (+300%) compared to Ionbond’s hydrogenated DLC coatings with a reference hardness of 25 GPa. The advanced coating technology used to deposit Tribobond 49 creates a smoother coating which can be used as-deposited, without any post-polishing, compared to current hydrogenated and hydrogen free ta-C coatings. The coating hardness has been increased by 40%, up to 35-40 GPa, compared with reference standard hydrogenated DLC coatings. The improved hardness and wear resistance of Tribobond 49, in combination with the low friction properties and smooth surface, creates a new performance and life time standard for DLC coatings.


Tribobond 49 is developed for high performance automotive and motorsport applications where high contact loads, friction and wear are present in demanding tribological environments. Highly loaded valve, crank train, engine components and fuel injection components are potential candidates for Tribobond 49.
