Joining its expertise in DLC coatings with its engineering capabilities for high-volume automotive products - resulted recently in the launch of a brand new range of DLC coatings, dedicated to the automotive engine market. This family of reliable and high-performance coatings is marketed worldwide under the trade name Dylyn® Plus. The unique composition and structure of Dylyn® Plus makes it the most reliable and highest performance surface solution available on the market for automotive engine components.

 

 

UNIQUE BENEFITS

  • Coating properties are fine-tuned to meet exactly the requirements of each application.
  • Extremely low coefficient of friction properties are attainable in combination with high hardness and excellent adhesion.
  • Worldwide customer-oriented coating teams are supported by extensive R&D facilities.
  • Dylyn® Plus is based on Bekaert's worldwide recognized success of DLC Cavidur® coatings for racing engine applications.

AUTOMOTIVE ENGINE PARTS THAT PERFORM BETTER WITH BEKAERT DYLYN® PLUS

  • Camshafts
  • Lifters / tappets
  • Piston rings
  • Wrist pins
  • Gears
  • Fuel injection and pump components

IN BRIEF BEKAERT DYLYN® PLUS

                                       
                         low friction                   high hardness

VALVE TRAIN COMPONENTS

  • Camshafts
  • Tappets
  • Lifters
  • Finger followers
  • Valves
  • Retainers


Due to the low coefficient of friction, Dylyn® Plus reduces frictional losses and increases the lifetime of valve train components.

                  

Wrist pin

Dylyn® Plus helps to reduce galling and improves liftetime performance.

PISTON ASSEMBLIES

Piston rings

The high wear resistance of Dylyn® Plus coatings in cold welding areas leads to an extended lifetime and an increased reliablility of components.

TECHNOLOGICAL LEADERSHIP

Bekaert is a financial healthy company able to keep up with the latest developments in the field of diamond-like coatings. Employing over 260 people at its central R&D facility, it is always possible to respond quickly to questions regarding surface and material engineering.

COMPARISON OF BEKAERT DYLYN® PLUS WITH OTHER COATINGS

  • The achieved coefficient of friction is well below that of other coatings offered today. Therefore the friction losses can be reduced, resulting in higher output and/or reduced consumption.
  • Dylyn® Plus also provides a good back-up for situations in which the tribological system has to run without its usual lubrification, thus resulting in an increased reliability and enlarged lifetime of the components.
