Creator of Composite Diamond Coating®

Surface Technology, Inc. is the creator and technical leader of CDC - Composite Diamond Coating®, an exceptionally engineered coating of electroless nickel with fine diamond. The synergy of these materials makes CDC an exceptionally hard and wear resistant coating. CDC conforms to even the most complex geometries and is an excellent replacement for chrome plating. STI makes CDC available via coating services from its production facility as well as chemical products sold directly, through a network of distributors, and by agreement with licensees worldwide.

Contact STI for One-Plate® Electroless Nickel solutions, the simplest EN in the world. These One-Plate® systems use just one “Q” solution for both bath make-up and replenishment. This innovation by STI overcomes the many shortcomings of using three A, B, and C solutions. Available in low, medium, high phosphorous, and composite EN varieties. Naturally, all are RoHS compliant.”

Composite Diamond Coating®™ - Golf Applications

Surface Technology, Inc. has made the golf industry's long awaited dream a clubs coated with diamond, the hardest material known to man. The effectiveness of Composite Diamond Coating®  for golf clubs has been proven by repeated testing, and was recognized by the US Patent and Trademark Office in the granting of two US patents.

Composite Diamond Coating®  is used by manufacturers in numerous industries worldwide. This technology, now available to golf equipment manufacturers, will provide the following performance advantages and new design opportunities.


  • The USGA has ruled that Composite Diamond Coating® conforms to USGA rules (USGA Decision Number 94-307).
  • In independent robotics testing, golf balls struck by clubs featuring Composite Diamond Coating® achieve faster velocities and over 7% greater distances than balls struck by identical uncoated clubs.
  • Composite Diamond Coating® has no affect on ball dispersion.
  • Composite Diamond Coating® offers multiple advantages essential to golf equipment including unsurpassed hardness, outstanding anti-corrosion properties, high impact durability and abrasion resistance. This unique coating's exceptional wear resistance preserves the precise roughness on the faces of wedges to provide longer lasting and more consistent club performance.
  • Composite Diamond Coating® conforms perfectly to all shapes including even the most intricate grooves and engravings on golf clubs.
  • Composite Diamond Coating® can be applied to all metals currently used to produce golf clubs including stainless steel, titanium, and aluminum; cast, forged or milled. Moreover, the features of Composite Diamond Coating® will allow companies to manufacture golf clubs using less costly metals such as low carbon steel.
  • Composite Diamond Coating® will provide golf club manufacturers with new opportunities for unique weight distribution designs.
  • The attractive appearance of Composite Diamond Coating® can be tailored to meet a variety of cosmetic preferences, and may also be subsequently finished by polishing, blasting, tumbling, varnishing, painting, or any other method.

During its golf application development program, Surface Technology, Inc. enlisted an independent laboratory to evaluate the performance of golf clubs featuring Composite Diamond Coating®. Testing was performed outdoors on an electro-mechanical hitting machine on a field duplicating fairway conditions. All clubs (coated and uncoated) were constructed with Dynalite Gold® frequency matched shafts and had identical lofts, lies, head weights and swing weights. Precise center hits were done on all clubs with Titleist® DT90 balls. Weather conditions were ideal for testing.

This testing demonstrated an increase in ball distance of more than 7% is achievable from Composite Diamond Coating® golf clubs. The following illustrates one example from this testing.
