Tribobond™ 42 DLC

DLC coating for highly loaded industrial compo-nents 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 system. Apart from automotive, multiple components of industrial machinery benefit from Tribobond 41 through reduction of wear and friction, thus extending their lifetime and maintenance intervals. The coating shines in particular in applications with marginal lubrication and high loads.


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. In industrial applications Tribobond 42 is widely used for wear applications in aerospace, oil and gas, power generation, racing and other industries.
