Tribobond™ 46 DLC

DLC coating for high temperature industrial components and high volume automotive applications

Ionbond’s Tribobond™ 46 DLC, CrN + a-C:H:W, coating is based on the excellent load bearing and high temperature properties of Tribobond™ 30 (CrN), with an extra low friction running-in coating on top. This results in a coating system that combines excellent running-in properties, a high load carrying capacity and fatigue resistance with a good wear resistance and a low coefficient of friction.


Hard and wear resistance coatings like Tribobond™ 46 DLC offer high load bearing capabilities combined with excellent counterparts protection in order to extend the lifetime of the components.
