Tribobond™ 40 DLC

Traditional DLC coating for industrial components and high volume automotive applications

Ionbond’s Tribobond™ 40 DLC, a-C:H:W, is one of the most well-proven DLC coatings for tools, industrial and automotive components. It combines excellent running-in properties with a good wear resistance and low friction properties. Tribobond™ 40 DLC exhibits excellent performance on industrial components in aerospace, transmissions, wind energy and roller bearing applications.


As a very hard and wear resistant coating, Tribobond™ 40 DLC offers a high load bearing capability in combination with an excellent counterparts protection, which extends the lifetime of both components in interaction. The ductile behavior of this material makes it very suitable for contacts in rolling motions.
