Tribobond™ 41 DLC

DLC coating with superior sliding properties for high volume automotive applications

Ionbond’s Tribobond 41 DLC a-C:H:W + a-C:H coating has been used for high  volume  automotive  production  for  many  years.  It  combines good running-in properties with a high wear resistance and very low friction.  The  coating  is  very  well  suited  for  pure  sliding  conditions  in  tribological   contacts.  Tribobond 41 exhibits 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 41 DLC in order to improve the robustness and lifetime of fuel pump and fuel injection systems. Apart from automotive, multiple components of industrial machinery benefit from Tribobond 41 DLC 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 41 DLC is applied on components in order to minimize friction losses in engines and engine subsystems, such as oil/water pumps, compressors, and power steering, in order to increase the efficiency and  reduce  the  fuel  consumption  in  transportation.  In industrial applications Tribobond 41 is widely used for wear applications in aerospace, oil and gas, power generation, racing and other industries.
