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.”

ENBO™ 70


The ENBO™ 70 system is a bright electroless nickel - boron alloy process designed to deposit a uniform, nickel - boron alloy onto a great variety of metals, alloys, and non-conductors.

  • The ENBO 70 system is available in convenient packaging where ENBO 70 A and ENBO 70 B are used for bath make-up, and ENBO 70 R and ENBO 70 Z are used for replenishment.

Some advantages of the ENBO 70 system are:

  • High as-plated hardness
  • Low bath operating temperature
  • Low electrical resistivity

The ENBO 70 system electroless nickel processes meets or exceeds AMS 2399
