Tribobond™ 42 DLC

DLC coating for highly loaded industrial components and high volume automotive applications

Ionbond’s Tribobond™ 42 DLC, CrN + a-C:H, coating is engineered for very highly loaded components. It combines a high load carrying capacity and fatigue resistance with a high wear resistance and still exhibits very low friction properties.

Tribobond™ 42 DLC presents an excellent performance on valve train (e.g. tappets) and crank train components (e.g. piston pin/ring). State of the art common rail and unit injector components are protected with Tribobond™ 42 in order to improve the robustness and lifetime of fuel pump and fuel injection systems.


Ionbond’s Tribobond™ 42 DLC is especially designed to run under combined rolling and sliding situations. It combines properties of extreme fatigue resistance, a very low coefficient of friction, and high wear resistance within one coating system. In operation, this coating architecture provides extreme protection of the coated part, as well as the counterpart.
