About Diamonex®

Diamonex® provides unique coating solutions to improve performance and extend component life in diverse industries and challenging operating environments.

Diamonex® has been developing diamond-like carbon (DLC) and polycrystalline diamond coating (CVD) technologies since 1990. In addition to coatings, Diamonex® has developed unique ion source technology designed specifically for the deposition of high-quality DLC and DLC-like nano composite films. Our radio frequency (RF) DLC process delivers uniform conformal coatings on complex geometries, while our ion-beam technology provides high-quality coatings more suitable for line-of-sight process geometries.

Our Application Engineers will work with your engineers to tailor and optimize robust coating processes and testing protocols to deliver coating solutions that meet your application and quality requirements.  With over 46 patents generated by our R&D team, our goal is to continually enhance the quality and service we provide our customers.

Typical DLC Substrates:


  • Stainless Steel
  • Aluminum and Aluminum Alloys
  • Tungsten Carbides
  • Titanium and Titanium Alloys
  • Various Tool Steels


  • Alumina
  • Zirconia
  • Aluminum Nitride
  • Various Ceramics




Optical Coatings

  • CLEARSHIELD – Optical Data Capture Windows
  • EVERSCAN™ – Super-hard coating designed to increase life of laser based POS scanner and access ID windows
  • DIAMONDSHIELD® – Provides plastics with a comparable scratch resistance to glass.

DLC Coating

Superior wear / abrasion resistance, biocompatible, low friction,  excellent chemical resistance, high hardness, no post processing required.

CMP Pad Conditioners

CVD diamond coating inert to all process chemistries; high-purity SiC substrates; low pad cut rate with improved material removal rates; a more gradual decay of pad cut rate provides consistent pad texture and longer pad life.


“Christopher Tool & Mfg. has worked with Diamonex for many years on highly visible development and production programs in the aerospace industry. The development projects are frequently completed under pressure and Diamonex has always performed at the highest levels. They have shown top level expertise of DLC coating technology while developing new processes and efficient execution to help us overcome challenging situations. In order for us to meet our customer’s production requirements, Diamonex communicates with us on a regular basis to set priorities which helps us be an effective supplier to major programs such as the F-35 Joint Strike Fighter and GE414 Engine. Diamonex is a vital component in our supply chain.”
