Diamonex® DLC coatings enhance the tribological properties of a broad range of substrate materials in demanding operating environments. The coatings are superhard, conformal with extremely low friction consisting of amorphous carbon with diamond-like bonds. Our amorphous coating has no large crystallites, and mimics the surface characteristics of the underlying substrate. The Diamonex® DLC coatings can be applied to both flat surfaces and 3D parts using either Direct Ion Beam or RF Plasma deposition techniques.


  • Coatings for metals, ceramics, plastics, glass
  • Complex geometry parts processing
  • Prototype, batch and volume production
  • Product design / development, applications engineering, QC / analytical and tooling design services.


  • Ion-Beam PECVD
  • Radiofrequency (RF) PECVD

DLC is an amorphous carbon that exhibits short-range order bonding similar to crystalline or polycrystalline diamond, with additional graphitic component, and some hydrogen may be present.


  • Supreme wear & abrasion resistance
  • High Hardness (8-25 GPa – Adjustable) – Extends lifetime & prevents fretting/galling
  • Low Coefficient of Friction ((COF) or μf) 0.05 – 0.25 – Improved efficiency, reduced power requirements
  • Highly Conformal – Thin coatings: 0.005 – 10 microns – Eliminates the need for subsequent machining
  • Biocompatible – Can be used for coating medical implants
  • Corrosion Protection – Suitable replacement for Hard Chromium (HexCr – HCr 6)

Diamonex® coatings can be optimized to provide both wear resistance and electrostatic protection for a variety of semiconductor ceramic components which extends component life and reduces potential contamination caused by component wear.

Precision Engineering

Diamonex® coatings are being used to provide a protective barrier for use on high-speed rotary air bearings to prevent galling and reduce the coefficient of friction.

Furthermore, these coatings are also being used to provide wear and abrasion resistance for use in high frequency operations.


Diamonex® provides automotive designers with the opportunity to increase operating efficiencies by reducing friction and increasing component life.

Medical and Orthopedic

Biocompatible, High Film Cohesion

The Diamonex® range of thin film medical coatings have been specifically developed to provide hermetic and biocompatible coatings with excellent cohesion properties and wear couples.

Extreme applications have included artificial joints and heart-assist devices where coating integrity and adhesion, combined with the need for extended component life and the ability to interface with the human body without cellular degradation, are of paramount importance.

Diamonex® coatings take component performance to the next level!
