Diamond-Like Carbon Coating (DLC) is the ultimate performance coating, offering a wear-resistant chemical barrier for metal, ceramic, glass, and plastic, normally deposited at temperatures below 150°C.

DLC is ultra resistant to abrasive and adhesive wear, rendering it suitable for use in both rolling and sliding applications that experience extreme contact pressure. Unlike graphite, DLC provides high lubricity at both ambient atmosphere and at vacuum.

We offer three specialized DLC processes: Advanced Auto Pro (AAP), Advanced Mold Pro (AMP) and Advanced Combo Pro (ACP).


DLC films are amorphous and consist of a mixture of sp2 (graphite) & sp3 (diamond) phases. The film properties are strongly dependent on the flux characteristics of the chosen deposition process (PVD sputter or evaporation and PACVD), metal and hydrogen content within the film, sp2:sp3 ratio, substrate bias voltage, ion energy and density, as well as substrate temperatures.

Our DLC Processes


A DLC process which helps automotive designers achieve the EU6 emission limit and ensures component reliability with a surface solution that combines reduced friction and excellent wear protection.

Designed for highly stressed components, AAP is characterized by its extremely smooth surface and self-lubricating properties. Even in low lubrication conditions, the coating decreased the coefficient of friction significantly, performing as well as in well-lubricated conditions.


  • Excellent abrasive and adhesive wear protection in tribological systems
  • Low friction
  • Ensures optimal function in lubrication deprived conditions
  • Increases lifecycle
  • Contributes towards lowering emissions


  • Pistons, rings and pins
  • Finger followers
  • Tappets
  • Injection components 


This Plasma-Assisted Chemical Vapour Deposition (PACVD) process activates chemical reactions through plasma excitation and ionization. It has been designed with the engineering, automotive, plastics processing, and semiconductor industries in mind. To guarantee best quality and performance, AMP coating is applied in a clean environment at a temperature range of 180°C – 220°C.


  • Low surface energy
  • Low micro porosity
  • High hardness
  • Low friction
  • Biocompatible
  • Excellent adhesion
  • Can be tailored with respect to electrical conductivity and hydrophobic and hydrophilic behaviour


  • Components for the automotive, engineering, and semiconductor industries
  • Moving and form-giving mold components
  • Caps and closures
  • Ejector pins and bushings
  • Blow mold and forms for PET cores and bottles


This process is deposited by a combination of PVD and PACVD. It has been designed with racing and high performance engine applications in mind. The ACP coating is applied at a temperature range of 180°C – 350 °C.


  • Enhances performance
  • Reduces friction
  • Reduces wear and extends part life
  • Greater performance and reliability
  • Protects both coated component and uncoated counterpart


  • Piston rings
  • Valve train components
  • Oil pump shafts


Due to their unique combination of properties, DLC coatings are extremely effective in many other tribological and wear applications, such as:

  • Mold and mold components
  • Engines of modern super-sport motorcycles
  • Formula 1 race cars
  • NASCAR vehicles
  • Magnetic storage media like hard disk platters and hard-disk read heads
  • Diesel injection pumps
  • Dry shaping of difficult exposed surfaces of wood and aluminum
  • Human heart pump implants
  • Electrical insulator of copper devices for chip cooling
  • Encapsulants for photovoltaic solar cells
  • Laser barcode scanner windows in supermarkets
  • Textile industry parts, etc.
